Filling. A. Fill areas to be filled in 8 to 12 inch maximum layers and compact to a density of at least 95 percent of maximum density as determined by AASHTO T-180. B. Compact materials at a moisture content within +2% of the optimum. If required, add water or permit material to dry until the proper moisture content for specified compaction is obtained. C. Compact materials at a moisture content within +2% of the optimum. If required, add water or permit material to dry until the proper moisture content for specified compaction is obtained. D. Field test density of compacted fill layer by Field Density Test ASTM D1556 or D2922 prior to placement of succeeding lifts. At a minimum, make at least one test per layer for every 8,000 square feet of non-structural area. E. A laboratory retained by Contractor and approved by Engineer shall make field density tests as specified. One Xxxxxxx Test (ASTM D698 or ASTM D1557) for each source of fill used shall be made by laboratory. Additional field tests will be required for each test not meeting required density. Costs of all tests will be paid by Contractor and included in Contract price.
