The Contractor’s “QSD” shall amend the SWPPP/WPCP, graphically and in narrative form, whenever there is a change in construction activities or operations which may affect the discharge of significant quantities o f pollutants to surface waters, ground waters, municipal storm drain systems, whenever there is a change in disturbed area, and/or or when deemed necessary by the City. The SWPPP/WPCP shall be amended if, at any time, the implementation of the SWPPP/WPCP i s not effectively achieving the objective of compliance with the CGP. Amendments shall show additional control measures or revised operations, including those in areas not shown in the initial SWPPP/WPCP, which are required on the project to control water pollution effectively. Amendments to the SWPPP/WPCP shall be closely coordinated with the Contractor’s Qualified SWPPP Practitioner (QSP) within five ( 5) working days. In emergency situations that require immediate changes at the project site, the Contract or’s QSP shall implement the necessary measures and notify the Project Manager and Contractor’s QSD of the changes.

2. Below 140 degrees F for HMA with modified binder

3.3 SPREADING AND COMPACTING EQUIPMENT

B. Install and maintain grade and slope reference.

C. The screed must be heated and produce a uniform HMA surface texture without tearing, shoving, or gouging.

D. The paver must not leave marks such as ridges and indentations unless you can eliminate them by rolling.

E. Rollers must be equipped with a system that prevents HMA from sticking to the wheels. You may use a parting agent that does not damage the HMA or impede the bonding of layers.
479
City of Pittsburg, California December 2022

ASPHALT PAVING 32 12 16 - 13
F. In areas inaccessible to spreading and compacting equipment:

1. Spread the HMA by any means to obtain the specified lines, grades and cross sections.

2. Use a pneumatic tamper, plate compactor, or equivalent to achieve thorough compaction.

3.4 MATERIAL TRANSFER VEHICLE:

A. The material transfer vehicle must have sufficient capacity to prevent stopping the paver and must be capable of:

1. Either receiving HMA directly from trucks or using a windrow pickup head to load it from a windrow deposited on the roadway surface.

2. Remixing the HMA with augers before transferring into the paver’s receiving hopper or feed system.

3. Transferring HMA directly into the paver’s receiving hopper or feed system.

3.5 METHOD COMPACTION EQUIPMENT:

A. For method compaction, each paver spreading HMA must be followed by 3 rollers:

1. One vibratory roller specified designed to compact HMA. The roller must be capable of at least 2,500 vibrations per minute and must be equipped with amplitude and frequency controls. The roller’s gross static weight must be at least 7.5 tons.

2. One oscillating-type pneumatic-tired roller at least 4 feet wide. Pneumatic tires must be of equal size, diameter, type, and ply. The tires must be inflated to 60 psi minimum and maintained so that the air pressure does not vary more than 5 psi.

3. One steel-tired, 2-axle tandem roller. The roller’s gross static weight must be at least 7.5 tons.

3.6 SURAFCE PREPARATION:

A. Before placing HMA, remove loose paving particles, dirt, and other extraneous material by any means including flushing and sweeping.

B. Prepare subgrade to receive HM A under the sections for the material involved.

Subgrade must be free of loose and extraneous material.

3.7 TACK COAT:

A. Apply tack coat in accordance with Section 39-2.01C(3)(f) of the State Standard Specifications.

City of Pittsburg, California December 2022

ASPHALT PAVING 32 12 16 - 14
B. Apply tack coat:

1. To existing pavement including planed surfaces.

2. Between HMA layers

3. To vertical surfaces of:

a. Curbs
b. Gutters
c. Construction joints.

C. Coat surfaces of manholes and catch basins.

D. Equipment for the application of tack coat must comply with Section 37 -1.03B, “Equipment” of the State Standard Specifications.

CSS1/CSS1h asphaltic emulsion
New HMA (between layers) 0.02
Concrete Pavement and existing
asphalt concrete surfacing

0.03 Planed pavement 0.05
F. If a stress absorbing membrane interlayer as specified in Section 37-2.05, “Stress Absorbing Membrane Interlayers”, of the State Standard Specification is applied, the tack application rates for new HMA apply.

G. Notify the Project Manager if you dilute asphaltic emulsion with water. The weight ratio of added water to asphaltic emulsion must not exceed 1 to 1.

H. Apply tack coat to vertical surfaces with a residual rate that will thoroughly coat the vertical face without running off.

I. Immediately in advance of placing HMA, apply additional tack coat to damaged areas or where loose or extraneous material is removed.

3.8 LONGITUDINAL JOINTS
A. Longitudinal joints in the top layer must match lane lines. Alternate the longitudinal joint offsets in the lower layers at least 0.5 foot from each side of the lane line.

B. A vertical longitudinal joint of more than 0.15 foot is not allowed at any time between adjacent open lanes to traffic.

C. For an HMA thickness of 0.15 foot or less, the distance between the ends of t he adjacent surfaced lanes at the end of each day’s work must not be greater than can be completed in the following day of normal paving.

D. For an HMA thickness greater than 0.15 foot, you must place HMA on adjacent travel way lanes or shoulder such that at the end of each work shift the distance between the ends of HMA layers on adjacent lanes is from 5 to 10 feet. Place additional HMA along the transverse edge at each lane’s end and along the exposed longitudinal edges between adjacent lanes. Hand rake and compact the additional HMA to form temporary conforms. Place Kraft paper or other authorized release agent under the conform tapers to facilitate the taper removal when paving activities resume.

E. If placing HMA against the edge of existing pavement, saw cut or grind the pavement straight and vertical the joint to the full depth and remove extraneous material.
