In addition and complementary to any other indemnification provided in these bid documents, and except for the active negligence or willful misconduct of an Indemnitee (as hereinafter defined), the Contractor hereby assumes liability for and shall defend (at Indemnitees’ option), indemnify, protect and hold harmless the City and its project consultants and engineers, officers, agents, and employees (“Indemnitees”) from and against any and all claims, charges, damages, demands, actions, proceedings, losses, stop notices, costs, expenses (including but not limited to attorney fees with counsel acceptable to the City), judgments, civil fines and penalties, liabilities of any kind or nature whatsoever, which may be sustained or suffered by or secured against the Indemnitees arising out of or encountered in connection with this Agreement or the performance of or failure to perform the work including, but not limited to, death of or bodily or personal injury to persons or damage to property, including property owned by or under the care and custody of the City, that may arise from or be caused, in whole or in part, by any negligent or other act or omission of the Contractor, its officers, agents, employees or subcontractors including, but not limited to, liability arising from:

1. Any dangerous, hazardous, unsafe or defective condition of, in or on the premises, of any nature whatsoever, which may exist by reason of any act, omission, neglect, or any use or occupation of the premises by the Contractor, its officers, agents, employees, or subcontractors;

2. Any operation conducted upon or any use or occupation of the premises by the Contractor, its officers, agents, employees, or subcontractors under or pursuant to the provisions of this contract or otherwise;

3. Any act, omission or negligence of the Contractor, its officers, agents, employees, or subcontractors;

4. Any failure of the Contractor, its officers, agents or employees to comply with any of the terms or conditions of this contract or any applicable federal, state, regional, or municipal law, ordinance, rule or regulation; and

5. The conditions, operations, uses, occupations, acts, omissions or negligence referred to in subsubsections (1), (2), (3), and (4), existing or conducted upon or arising from the use or occupation by the Contractor on any other premises in the care, custody and control of the City.

The Contractor also shall indemnify the City and pay for all damage or loss suffered by the City including but not limited to damage to or loss of the City’s property, to the extent not insured by the City and loss of the City’s revenue from any source, caused by or arising out of the conditions, operations, uses, occupations, acts, omissions or negligence referred to in sub-subsections (1), (2), (3), (4), and (5).

The Contractor’s obligations under this section apply regardless of whether or not such claim, charge, damage, demand, action, proceeding, loss, stop notice, cost, expense, judgment, civil fine or penalty, or liability was caused in part or contributed to by an Indemnitee. However, without affecting the rights of the City under any provision of this agreement, the Contractor shall not be required to indemnify and hold harmless the City for liability attributable to the active negligence of the City, provided such active negligence is determined by agreement between the parties or by the findings of a court of competent jurisdiction. In instances where the City is shown to have been actively negligent and where the City’s active negligence accounts for only a percentage of the liability involved, the obligation of the Contractor will be for that entire portion or percentage of liability not attributable to the active negligence of the City.

27 The Contractor shall obtain executed indemnity agreements with provisions identical to those set forth here in this section from each and every subcontractor or any other person or entity involved by, for, with or on behalf of the Contractor in the performance of this Agreement. In the event the Contractor fails to obtain such indemnity obligations from others as required here, the Contractor shall be fully responsible according to the terms of this section.

Failure of the City to monitor compliance with these requirements imposes no additional obligations on the City and will in no way act as a waiver of any rights hereunder. This obligation to indemnify and defend the City as set forth here is binding on the successors, assigns or heirs of the Contractor and shall survive the termination of this Agreement or this section.

This Indemnity shall survive termination of the Agreement of Final Payment hereunder. This Indemnity is in addition to any other rights or remedies that the Indemnitees may have under the law or under any other contract documents or Agreements. In the event of any claim or demand made against any party which is entitled to be indemnified hereunder, the City may, in its sole discretion, reserve, retain or apply any monies to the Contractor under this Agreement for the purpose of resolving such claims; provided, however, the City may release such funds if the Contractor provides the City with reasonable assurance of protection of the Indemnitees’ interests. The City shall, in its sole discretion, determine whether such assurances are reasonable.
(b) Insurance Requirements – see provisions of the Construction Agreement (c) Additional Requirements

1. The Contractor shall ensure that subcontractors, and any other party involved with the project that is brought onto or involved in the project by the Contractor, provide the same minimum insurance coverage required of the Contractor.

If the Contractor’s existing coverage includes a deductible or self-insured retention, the deductible or self-insured retention must be declared to the City. At that time the City shall review options with the Contractor, which may include reduction or elimination of the deductible or self-insured retention, substitution of other coverage, or other solutions.

4. The City reserves the right at any time during the term of the contract to change the amounts and types of insurance required by giving the Contractor ninety (90) days advance written notice of such change. If such change results in substantial additional cost to the Contractor, the City will negotiate additional compensation proportional to the increased benefit to City.

5. For purposes of applying insurance coverage only, all contracts pertaining to the project will be deemed to be executed when finalized and any activity commences in furtherance of performance under this Agreement.

6. The Contractor acknowledges and agrees that any actual or alleged failure on the part of the City

17.b
Packet Pg. 312 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

28 to inform the Contractor of non-compliance with any insurance requirement in no way imposes any additional obligations on the City nor does it waive any rights hereunder in this or any other regard.

7. The Contractor will renew the required coverage annually as long as the City, or its employees or agents face an exposure from operations of any type pursuant to this agreement. This obligation applies whether or not the agreement is canceled or terminated for any reason. The insurance shall include but not be limited to products and completed operations and discontinued operations, where applicable. Termination of this obligation is not effective until the City executes a written statement to that effect.

8. The Contractor agrees to waive its statutory immunity under any workers’ compensation statute or similar statute, in relation to the City, and to require all subcontractors and any other person or entity involved in the project contemplated by this Agreement to do likewise.

9. Requirements of specific coverage features are not intended as limitations on other requirements or as a waiver of any coverage normally provided by any given policy. Specific reference to a given coverage feature is for purposes of clarification only as it pertains to a given issue, and is not intended by any party or insured to be all inclusive.

10. Any provision in any of the construction documents dealing with the insurance coverage provided pursuant to these requirements is subordinate to and superseded by the requirements contained herein. These insurance requirements are intended to be separate and distinct from any other provision in this agreement and are intended by the parties here to be interpreted as such.

11. All liability coverage provided according to these requirements must be endorsed to provide a separate aggregate limit for the project that is the subject of this agreement and evidencing products and completed operations coverage for not less than two (2) years after issuance of a final certificate of occupancy by all appropriate government agencies or acceptance of the completed work by the City.

12. The Contractor agrees to be responsible for ensuring that no contract used by any party involved in any way with the project reserves the right to charge the City or the Contractor for the cost of additional insurance coverage required by this Agreement. Any such provisions are to be deleted with reference to the City. It is not the intent of the City to reimburse any third party for the cost of complying with these requirements. There shall be no recourse against the City for payment of premiums or other amounts with respect thereto.

The Contractor shall bear the expenses of the Geotechnical investigation.

B. EXECUTION
a. General:

The subbase grade shall be excavated to within plus or minus 0.05 feet of design grade prior to the placement of native material fill. The design subbase grade shall be field verified and approved by the Engineer prior to the placement of the fill material. The Engineer shall determine the number and location of points to check for the subbase grade elevation compliance.

17.b
Packet Pg. 369 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

85 Native material fill shall be placed in maximum 8-inch lifts and compacted to 90 percent of maximum density at optimum water content per ASTM D 1557 unless otherwise specified on the Plans. Additional native soil lifts shall not be placed until previous lifts have attained the specified compaction requirement and are approved by both the on-site geotechnical representative and the Engineer.

b. Preparing Areas To Be Filled:

All vegetation and objectionable material shall be removed by the Contractor from the surface upon which the fill is to be placed and any loose and porous soils shall be removed or compacted to a depth specified by the Geotechnical Engineer. The surface shall then be plowed or scarified to a minimum depth of 6 inches until the surface is free from uneven features that would tend to prevent uniform compaction by the equipment to be used.

When placing fill in horizontal lifts adjacent to areas sloping steeper than 5:1 (horizontal:vertical), horizontal keys and vertical benches shall be excavated into the adjacent slope area. Keying and benching shall be sufficient to provide at least 6-foot wide benches and a minimum of 4 feet vertical bench height within the firm natural ground, firm bedrock or engineered compacted fill. No compacted fill shall be placed in an area subsequent to keying and benching until the area has been reviewed by the Geotechnical Engineer. Material generated by the benching operation shall be moved sufficiently away from the bench area to allow for the review of the horizontal bench prior to placement of fill.

After the foundation for the fill has been cleared, plowed or scarified, it shall be disced or bladed by the Contractor until it is uniform and free from large clods, brought to the proper moisture content and compacted as specified.

c. Placing, Spreading and Compacting Fill Material:

The fill material shall be placed by the Contractor in thin layers that when compacted shall not exceed 8 inches for native material. Each layer shall be spread evenly and shall be thoroughly mixed during the spreading to obtain uniformity of material in each layer.

When the moisture content of the fill material is below that required by the Geotechnical Engineer, water shall be added by the Contractor until the moisture content is as required for the specified compaction.

When the moisture content of the fill material is above that required by the Geotechnical Engineer, the fill material shall be aerated by the Contractor by blading, mixing, or other satisfactory methods until the moisture content is as required for the specified compaction.

After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted by the Contractor to the specified density. Compaction shall be accomplished by sheepsfoot rollers, vibratory rollers, multiple-wheel pneumatic-tired rollers or other types of acceptable compacting equipment. Equipment shall be of such design that it shall be able to compact the fill to the specified density. Compaction shall be continuous over the entire area and the equipment shall make sufficient passes over the material to ensure that the desired density has been obtained.

Compacted fill slopes shall be overbuilt and cut back to grade, exposing the firm, compacted inner core. The slopes shall be overbuilt a minimum of five feet (5’). If the desired compaction is not achieved, the existing slope shall be overexcavated and reconstructed. The amount of overbuilding

17.b

The sealant shall contain no solvent, is prereacted and shall conform to the requirements of Caltrans SSP 37-400 Type 2. The crack sealant shall be a moderately high viscosity pavement preservation sealant intended for street and highway applications for sealing longitudinal and transverse cracks. The crack sealant shall be an effective barrier against damage from debris and moisture infiltration into cracks. The crack sealant shall be a Crafco 34521CA , Deery 80200CA or an approved equal. The crack sealant shall not contain constituents which react adversely with Slurry Sealcoat Material.

The crack sealant shall be melted in a jacketed double boiler type melting unit which is equipped with both agitation and recirculation systems. Direct fired or air heated machines shall not be allowed. The temperature of the heat transfer oil in the melting unit should not exceed 525 degrees Fahrenheit (274 degrees Celsius) during melting of the sealant. The melting unit must be capable of safely heating the sealant to 400 degrees Fahrenheit (204 degrees Celsius). The melting unit shall comply with the requirements of double jacketed boiler melters with effective agitation compliant with Appendix X1.1 of ASTM D 6690. Prior to applying the sealant, it shall be heated to a temperature between the recommended application temperature and the maximum heating temperature as illustrated on the sealant containers and Product Data Sheets. The crack sealant application life is to be monitored and if exceeded either extended or removed and discarded per the manufacturer’s installation instructions.

The pavement surface temperature shall be greater than 40 degrees Fahrenheit prior to crack sealant application.

Lower temperatures may result in reduced adhesion due to the presence of moisture or ice. If the pavement temperature is lower than 40 degrees Fahrenheit it may be warmed using a heat lance that puts no direct flame on the pavement. If installing crack sealant at pavement temperatures below 40 degrees Fahrenheit, extreme care should be used to insure that cracks are dry and free from ice, moisture and other contaminants. The crack sealant shall be maintained at its maximum temperature during applications when the pavement temperature is below 40 degrees Fahrenheit. If crack sealant is applied at night, applicators shall observe the pavement to assure dew does not form on the pavement surface.

Proper crack sealant adhesion requires cracks be thoroughly clean and dry immediately prior to crack sealant installation. Cracks shall be initially cleaned or widened using appropriate routing, brushing or blowing operations.

After initial cleaning and widening and after any debris removal is accomplished a final crack cleaning shall be accomplished by using a high pressure, 90 psi minimum, dry, oil free compressed air unit. Both sides of the prepared cracks shall be inspected to insure the high-pressure air has removed any remaining dust from the initial crack cleaning or routing. The surfaces of the prepared crack shall be inspected to insure adequate cleanliness and dryness prior to the application of the crack sealant. The contractor shall apply a herbicide to any cracks which exhibit vegetative growth 10 days prior to the commencement of construction activities.

17.b
Packet Pg. 373 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

89 Cracks 1/8 inch wide shall be routed to a minimum width of 3/8 inch and a minimum depth of ½ inch. Cracks ¼ inch wide and greater shall be routed for a minimum of 1/8 inch on both sides of the crack and a depth of ¾ inch.

It is recommended that cracks 1 ½ inches and greater not be crack sealed using the crack seal material specified under this Technical Specification Section. Following appropriate cleaning of the routed crack, sealant shall be applied to a slightly overfilled condition and then leveled with a squeegee across the crack with an overlap beyond the crack edges. This method of crack sealing results in an overband condition. Sealant overbands shall not exceed 1/16 inch in height above the pavement and not extend greater than 2 inches beyond crack edges. A detack agent shall be applied to the crack sealant product after application, as determined by the Engineer, to reduce the tackiness and resultant “tracking” of the sealant by vehicular traffic.

The crack sealant material shall conform to the following specifications when heated to its maximum heating temperature in accordance with ASTM D5167:

TEST METHOD CALTRANS SSP 37 – 400 TYPE 2
Cone Penetration ASTM D5329 40 maximum
Softening Point ASTM D36 205 degrees F (96 degrees C) minimum Flexibility ASTM D3111 modified Pass at 32 degrees F

Maximum Heating Temperature ASTM D6690 400 degrees F (204 degrees C) After the crack sealant material is applied, the debris, loose particles, dirt and pavement residue resultant from the crack cleaning and routing operation shall be removed and disposed of by the Contractor. The Contractor shall remove and dispose of the material resultant from the crack sealing cleaning operation with a vacuum street sweeper at the conclusion of the work day. The street area subject to crack sealing shall be closed to traffic until the crack sealant has sufficiently cured and is not subject to “tracking” by vehicular traffic. One-way traffic shall be maintained along the streets during crack sealing application work.

If equipment being used requires the cleaning out of pumps and plumbing, follow the manufacturer's clean out instructions. If solvent is used for clean out, insure that the solvent does not contaminate the sealant because sealant dilution and flash problems may occur.

Pallets of boxed product are protected with a weather resistant covering. During storage, the protective wrap must be kept on the pallets to prevent boxes from getting wet. If boxes are subjected to moisture, they may lose strength and crush resulting in pallet leaning. If rips in the pallet covering occur during handling, they should be repaired to help maintain packaging integrity. Pallets should be stored on a level surface which is dry and has good drainage.

Pallets should be not stacked because crushing of bottom layers may occur. Sealant material properties are not affected by packaging deterioration.

Since these sealants are heated to elevated temperatures, it is essential that operations be conducted in manners which assure safety of personnel. All associated with use of the material need to be aware of the hazards of using hot applied materials and safety precautions. Before use, the crew should read and understand product use and safety information on each box of sealant and the product MSDS. This sheet which is supplied with each shipment, describes the characteristics of the product as well as any potential health hazards and precautions for safe handling and use. User should check D.O.T. requirements for transportation at elevated temperatures above 212F (100C).

Skin contact with hot applied materials causes burns. Overexposure to fumes may cause respiratory tract irritation,

17.b
Packet Pg. 374 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

90 nausea, or headaches. Appropriate precautions need to be taken to prevent contact with the hot material and to avoid inhalation of fumes for everyone in the vicinity of the sealing operation. Safety precautions should include:
(1) Protective clothing to prevent skin contact with hot material; (2) Care when adding blocks of product to melters to reduce splashing; (3) Careful operation and control of wants or pour pots which are used to apply product; (4) Traffic and pedestrian control measures which meet or exceed local requirements to prevent access to work areas while product is still in a molten state; (5) Avoidance of material fumes; (6) Proper application configurations with a minimum amount of excesses of material; and (7) Appropriate cleanup of excessive applications or product spills.

The Contractor shall be compensated for the crack seal application by the pound of crack sealant material placed.

The Contractor shall furnish all labor, material, transportation and equipment for the installation of the crack sealant.

Street sweeping prior to crack sealing a street section, street sweeping at the conclusion of each day crack sealing work, clean up, traffic control, application of herbicide and protection of utility covers are incidental to the crack seal application costs.

The emulsion shall be introduced into the mixer by a positive displacement pump. The emulsion storage shall be equipped with a device that will automatically shut down the power to the emulsion pump and aggregate belt feeder when the level of stored emulsion is lowered to within 2” of the suction line.

A temperature indicating device shall be installed in the emulsion storage tank at the pump suction level.

The aggregate shall be proportioned using a belt feeder operated with an adjustable cutoff gate. The height of the gate opening shall be readily determinable.

The aggregate feeder shall be directly connected to the drive on the emulsion pump. The drive shaft of the aggregate feeder shall be equipped with an electronic digital revolution counter reading to the nearest full revolution of the aggregate delivery belt. The belt delivering the aggregate to the pugmill shall be equipped with a device to monitor the depth of the aggregate being delivered to the pugmill. The device for monitoring depth of aggregate shall automatically shut down the power to the aggregate belt feeder whenever the depth of aggregate is less than 70 percent of the target depth of flow. An additional device shall monitor movement of the aggregate belt by detecting revolutions of the belt feeder. The devices for monitoring no flow or belt movement, as the case may be, shall automatically shut down the power to the aggregate belt when the aggregate belt movement is interrupted. To avoid shutdowns caused by normal fluctuations in delivery rates, a delay of 3 seconds between sensing less than desirable storage levels of aggregate or emulsion shall be permitted.

Water delivery shall be adjusted through a diaphragm valve. Water flow rate shall be electronically displayed through a digital meter.

The mixer unit shall not be operated unless all electronic display and revolution counters are in good working condition and functioning and all metal guards are in place. All indicators required by these specifications shall be operational at all times.

The slurry sealcoat surfacing mixture shall be spread by means of a controlled spreader box. The spreader box shall be capable of spreading a traffic lane width and shall have strips of flexible rubber belting or similar material on each side of the spreader box and in contact with the pavement to positively prevent loss of slurry from the ends of the box. All spreader boxes shall be equipped with a motor driven auger when placing slurry sealcoat surfacing material. Rear flexible strike-off blades shall make close contact with the pavement, and shall be capable of being adjusted to the various crown shapes so as to apply a uniform surfacing coat. Flexible drags, to be attached to the rear of the spreader box, shall be provided as directed by the engineer. All drags and strike-off blades (rubbers) shall be cleaned or changed daily if problems with cleanliness and longitudinal scouring occur. The spreader box shall be clean, free of all slurry and emulsion, at the start of each work shift.

The pavement surface shall be crack sealed if required by the Contract Documents. Pavement striping shall be removed from the pavement surface and raised pavement markers shall be removed prior to the placement of slurry sealcoat material as required by the specifications. Any vegetation evident along pavement edges shall be treated with a herbicide a minimum of 5 days prior to slurry sealcoat application.

The contractor shall perform the cleaning and sweeping of the pavement surface, removal of striping and removal of raised pavement markers as an incidental cost to the placement of the slurry sealcoat material. The Contractor

17.b
Packet Pg. 380 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

96 shall remove and dispose of sweeping residue. A “kick” broom shall not be used for street sweeping. If water is used cracks shall be allowed to dry thoroughly before surfacing is applied. The surface of the pavement shall be determined to be sufficiently clean by the engineer prior to the application of slurry sealcoat material.

The Contractor shall protect all utility manhole covers, gratings, gas valve covers, water valve covers and survey monument covers from being coated with the slurry surfacing mixture. Suitable means of protection include covering the utility manhole covers, gratings, valve covers, and monument covers with a stick down paper or tape, polyethelyne material or cardboard cutouts shall be accomplished prior to the slurry sealcoat application. Upon completion of the slurry surfacing, the protection devices shall be removed the same day. Removable markings with distances shall be placed on the curb and gutter bordering the streets to identify the utility cover locations.

Wood lath shall be placed along A.C. pavement edges when no curb and gutter borders the street. The distance from the lath to the utility cover shall be written on the lath.

APPLICATION OF SLURRY SEALCOAT SURFACING MATERIAL
A. GENERAL
If required by the Engineer due to ambient temperature or dust conditions, the pavement surface shall be prewetted by fogging ahead of the spreader box. The rate of application of the fog spray shall be adjusted during the day to suit temperatures, surface texture, humidity, and dryness of the pavement but shall be kept to a minimum under all conditions.

The slurry sealcoat surfacing shall be of the desired consistency upon leaving the mixer. A sufficient amount of material shall be carried in all parts of the spreader at all times so that a complete coverage is obtained.

The slurry sealcoat surfacing mixture shall be uniformly spread on the existing surface within the rate specified. The slurry surfacing material shall not be placed when existing pavement temperature is below 60 degrees F, or when rain or freezing temperatures are forecast within the next 24 hours.

Evidence of solidification of the asphalt, balling or lumping of the aggregates, or the presence of uncoated aggregates will be cause for rejection of the slurry.

Slurry shall be applied in such a manner that no ridges shall remain.

The Contractor shall prevent slurry from being deposited on other than asphalt concrete surfaces and shall remove slurry from surfaces not designated to be sealed at no cost to the Owner. The method of slurry removal shall be approved by the Engineer.

At the direction of the Engineer, the Contractor shall repair and reseal all areas of the streets which have not been sealed properly or completely, at no cost to the Owner.

Where the completed slurry is not uniform in color, the street shall be treated to eliminate the color variation at the Contractor’s expense. The method of treatment shall be approved by the Engineer.

B. APPLICATION RATES
The slurry sealcoat surfacing material shall be spread at the following application rates:

Type 1 9 to 11 pounds of dry aggregate per square yard
Type 2 11 to 13.3 pounds of dry aggregate per square yard or
19 pounds of dry aggregate per square yard as indicated on the plans

17.b
Packet Pg. 381 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

97 The spread rate will be sufficient to fill all voids in the existing pavement and to place sufficient material to embed the largest size aggregate particles.

The completed spread rate will be within 10% of the rate determined by the Engineer after consideration of the surface texture of the existing pavement and the physical size of the aggregate in the mix.

The mixture shall be uniform and homogeneous after spreading on the surface and shall not show separation of the emulsion and aggregate after setting.

Any slurry sealcoat surfacing material to be spread in areas inaccessible to the controlled spreader box, may be spread by hand squeegees or other approved methods.

FIELD SAMPLING
During the performance of the Work, the Contractor will take at least two field samples of the mixed slurry per slurry mixer per day. The Wet Track Abrasion test sample shall not be transported until slurry has set as defined by ASTM D 3910. All field samples shall have the following values:

2. Modified CTM 382 to allow 1000 ± 100 gram sample.

3. Weigh a minimum of 500 grams of homogenized mixed slurry into a previously tarred quart can with a friction lid.

The lid shall be placed on the can to prevent loss of material during transportation. Place the can with the lid off in an oven and dry to constant mass at 230º ± 9ºF (110º ± 5ºC). Cool, reweigh and calculate the water content.

Subsection 6.4.4.7 of ASTM D 3910 may be modified to use a microwave oven for drying the specimen after the abrasion cycle and the debris has been washed off.

If the test results fail to meet the Specifications, the Contractor shall cease slurry laydown operation with the nonconforming mixer until it demonstrates the ability to comply with the Specifications.

No change in the proportions of the approved mix design will be permitted without the Engineer’s approval. If the

17.b
Packet Pg. 382 Attachment: Phase I Specifications VOL.1 (1190 : Approval of Plans and Specs - Imperial Avenue Extension Phase I)

98 Contractor changes it source of supply for either the aggregate or the emulsion, the mix design approval and the quality control procedures specified herein shall be repeated. Mixes used shall not deviate more than ± 1.0 percent from the approved proportion of emulsion. (Example: If the approved mix is 16 percent emulsion, then the emulsion content must be between 15 and 17 percent). The percentage of emulsion is based on the dry weight of aggregate.

MEASUREMENT AND PAYMENT
The Contractor shall be compensated for the slurry sealcoat application by the dry tons of aggregate placed. The Contractor shall furnish all labor, material, transportation and equipment for the installation of the slurry sealcoat application. Material includes asphaltic emulsion, crushed aggregates, set control additives, coloring additives, synthetic butadiene latex, water and all other required materials. Street sweeping, pavement striping removal, raised pavement marker removal, herbicide application to vegetation, clean up, traffic control and protection of utility covers are incidental to the slurry sealcoat application costs.

12. TACK COAT (SS1H) APPLICATION
Tack coat (SS1H) application shall be in accordance with Section 39-2.01C(3)(f) of the latest Caltrans Standard Specifications.
