00642.05 Definitions: <br /> Lot Size - A lot is the total quantity. of material or work produced per MD per project. The <br /> following circumstances will require a different Lot: <br /> • Portland Cement Stabilizing Agent is changed by 0.5 percent or more. . <br /> • Previous treated FDR material. must be re-pulverized and re-treated with Portland <br /> Cement Stabilizing Agent when required compaction is not achieve within 3 hours of the <br /> originaltreatment. <br /> Materials <br /> 00642.10 Materials: <br /> a) Pulverized Material -The reclaimed paving material shall conform to the following <br /> gradation. The gradation may be revised with the approval of the Engineer, but the top. <br /> size of the material shall not exceed 25% of the depth of the compacted recycled mat. <br /> Sieve Size % Passing <br /> *3 inch 100 <br /> 1 'h inch 95 -100 <br /> 1 .inch 90 -100 <br /> #4 55 - 75 <br /> *For Cross Street max aggregate size of existing aggregate will be allowed. <br /> b) Portland Cement Stabilizing Agents -Portland Cement stabilizing agent is required <br /> by•the mix design.
