At all times, the Contractor must maintain access to water valves. When the water valves are adjusted below grade, the Contractor shall provide swing ties, located outside the FDR-C section, identifying the exact location of the water valves. If requested by the Engineer, Owner or the City Water Department Specialist, the Contractor shall expose the valve for service.
C. Surface/Treatment Zone Preparation: Before FDR-C activities start, prepare the surface and treatment zone by:
1. Existing asphalt shall be sawcut to provide a smooth transition. Nothing herein shall be construed as relieving the Contractor of his responsibility for final clean up as provided in Section 4-1.13, “Cleanup,” of the State Standard Specifications.
2. Clear foreign matter including vegetation.
3. Remove standing water.
4. Referencing the profile and cross slope.

6. The FDR-C material to be treated shall be essentially free of irreducible particles greater than 6 inches in maximum dimension, contain less than about 10% irreducible particles greater than 3 inches in maximum dimensions and be determined by the Contractor to be satisfactory to not damage the mixer.

D. Pulverizing: Do not pulverize more material than can be mixed with cement, uniformly moisture conditioned, compacted and finish graded within one work shift.
No unpulverized material shall be left in-place. The 1 st cut width must be the full width of the pulverizing drum. Subsequent cuts must over lap previous cuts at least 4 inches, but not more than 12 inches.
Where the pulverizing drum stops in a longitudinal cut, the position of the drum shall be marked and a subsequent cut on that longitudinal alignment shall start at least 2 feet behind the mark.
If the pulverization encounters unstable conditi ons, notify the Engineer. The Engineer, with the Contractor’s assistance, will determine the extent of the problem area and the correction measures to be taken.
E. Applying Cement: Cement shall be applied in dry form.
Cement shall be uniformly spread over the work area. The design spread rate is 6.3 pounds/square foot, which is based on a dry soil weight of 124.8 pcf and a mix design of 5% cement.
Spreader speed shall be controlled based on the pan test speed to maintain an application rate of 6.0 to 6.9 pounds/square foot.
The spread area should not exceed the area which can be initially mixed, uniformly moisture conditioned and compacted within 2 hours.
F. Mixing: The FDR-C material shall be uniform ly mixed at least twice to the specified treatment depth. Mix until the mixture is visi bly uniform with no streaks or pockets of cement. The mixed material shall have a uniform color reaction with sprayed phenolphthalein alcohol indicator for the full specified treatment depth.
Water must be injected through the mixer. The injection rate of mixing water must be sufficient to produce a workable FDR-C material moisture content that is at least 4% above the optimum moisture content determined by ASTM D1557. A composite sample from 5 random locations shall be taken after initial mixing and tested under ASTM D2216 or D4959 (calibrated to ASTM D2216) to confirm the moisture prior to compaction.
Mixing shall occur in a series of parallel lanes of convenient width and length. Mixing of adjoining lanes shall overlap the previous lane by at least 4 inches, but not more than 1 foot, to provide continuity. Where the mixing drum st ops at the end of the lane, the position of the drum shall be marked and a subsequent lane on that longitudinal alignment shall start at least 2 feet behind the mark.
