d. Any processed material that has not been compacted and finished shall not. be <br /> left undisturbed for longer than 30 minutes. • <br /> e. Mixing shall begin as soon as possible after the cement has been spread and <br /> continued until the product is a uniform mixture of pulverized asphalt, base <br /> aggregate, soil, cement, water and meets gradation and moisture content <br /> requirements throughout the full design depth and width. <br /> f. The final mixture shall be pulverized to conform to section 00642.10 <br /> requirements. <br /> g. The final pulverization test shall be made at the conclusion of mixing operations. <br /> h. Cement shall not be placed on the grade more than 500 feet in front of the mixing <br /> equipment. <br /> 2) Cement Stabilizing Agent, Curing: <br /> a. After completion of final finishing, the surface shall be cured by application of a <br /> - bituminous or other approved sealing membrane It shall be applied as soon as • <br /> ossible .but not later than 4 hours after com letin finishin <br /> p ~ p g g operafions. The <br /> surface shall be kept continuously moist prior to application of curing material. <br /> b. For bituminous curing material, the FDR base surface shall be dense, free of all . <br /> loose and extraneous materials, and shall contain sufficient moisture to prevent <br /> excessive penetration of the bituminous material. The bituminous material shall <br /> be uniformly applied to the surface of the completed cement treated material. <br /> Bituminous curing material shall be CSS-1 h or CRS-1 h applied at an application <br /> rate of 0.20 gallons per a square yard of surface. <br /> c. Apply sand cover immediately after application of bituminous curing material <br /> sufficient to prevent pickup of the curing material <br /> 00642.45 Shaping and Surface Tolerances -Unless otherwise specified in the contract <br /> documents, the grade of the compacted stabilized reclaimed mat shall be finished to within one <br /> half (1/2) inch of the existing centerline and grade or as directed by the Engineer. Surface <br /> smoothness shall comply with 00641.45. <br /> As compaction nears completion, if necessary or as required by the Engineer, the surface shall <br /> be lightly scarified oc broom-dragged to remove imprints left by equipment or to prevent <br /> compaction planes. Compaction shall then be continued until uniform and adequate density is <br /> obtained. During the finishing process the surface shall be kept moist by means of water spray <br /> devices that will not erode the surface. Compaction and finishing shall be done in such a <br /> manner as to produce a dense surface free of compaction planes, cracks, ridges, or loose <br /> material. All finishing operations shall be completed within the time limit specified in 00642.43 a) <br /> 1). <br /> Excess FDR material remaining after finish grading shall be windrowed onto the gravel shoulder <br /> area for use as reclaimed base aggregate in shoulders. The reclaimed shoulder material shall <br /> be spread uniformly throughout the project and shall be supplemented, when necessary, with <br /> aggregate shoulder materials as directed by the Engineer. Finishing of the shoulder materials <br /> shall be according to the applicable requirements of Section 00640. <br /> 00642.49 Compaction -The Contractor shall perform initial rolling with a tamping foot roller <br /> until the roller pads walk out of the reclaimed mix. Shaping, to achieve planned profile and cross <br /> slope, should cut deep enough to remove the tamping foot roller marks. Repeated reclaiming <br /> <br /> and rolling may be required within two calendar days after the initial mixing processing and <br /> rolling to achieve the target density on the completed in-place recycled surface. The Contractor <br /> <br /> shall discontinue any type of rolling that result in `cracking, movement, or other types of distress <br /> until such time .that the problem can be resolved. If there is a significant change in mix <br /> proportions, weather conditions, or other controlling factors, the Engineer shall require <br /> <br /> Special Provisions --Job #4624 Page 9 of 15 <br /> <br />
