The compactor shall operate as specified herein without maintenance other than the contractor's recommended normal scheduled maintenance as established by a maintenance schedule prepared and submitted by the contractor prior to test.

4.5.2.2 Performance. Operate the compactor on a fill, built over a natural soil subgrade having an initial density of at least 90 percent when measured in accordance with ASTM D1557. The fill material shall correspond to two different groups of soils: a clayey sandy (sc) type with a plasticity index of 5-12, and a lean clay (cl) type with a plasticity index of 10-16, of the Soil

Classification Chart in ASTM D2487. Both types of soils, when compacted shall be within 2 percentage points of their respective optimum moisture content according to ASTM D1557, methods

B, C, or D. The compacted fill site shall be not less than 30 feet wide, with the actual width of the fill being a minimum of 3 feet wider than the compacted area as shown in figure 1. The fill may be placed prior to the start of compaction operation, during compaction operations, or the contractor may elect to till the natural soil in lieu of placing fill material. When hauling equipment is run over spread, un-compacted fill material, the fill site shall be scarified or tilled to a uniformly loose un-compacted condition. Spreading of the fill material shall be done with a grader. Spreading runs shall be only that necessary to reach the estimated un-compacted fill lift thickness. Water distribution equipment may be used as required. The material to be compacted shall be of sufficient thickness, initially, to give a compacted lift of at least 6-inches. The laboratory density of the soil to be compacted shall be determined in accordance with ASTM D1557, method optional. Compaction operations may be stopped by the contractor only after the following conditions have been met: Exactly 1 continuous hour has elapsed from the time the test has begun to determine whether or not the compactor is successfully able to compact the type(s) of soils described herein to 1500 cubic yards per hour with the minimum lift and test site dimensions/restrictions cited herein; and, the soils tested have been

Not for Resale, 06/21/2016 07:23:10 MDTNo reproduction or networking permitted without license from IHS compacted to 90 percent of maximum density at optimum water content according to ASTM D1557.

The time used in density testing shall not be counted as part of the ten (10) hour operating time specified herein. Density measurements shall be taken at points along the test strip using the pattern shown on figure 1 at intervals of 200 feet. In addition, a minimum of three (3) samples shall be taken at intervals of 100 feet and at random locations specified by the Government. Nuclear density testing shall be accomplished according to ASTM D6938, direct transmission method. The depth of measurement shall correspond to the compacted soil layer thickness (minus 1 inch maximum). Oven dried laboratory soil moisture content tests shall be used to check, and correct if necessary, the nuclear moisture reading. An achieved full depth fill material density of less than 95 percent of maximum density at optimum water content according to ASTM D1557, or compacted fill layer thickness of less than 6 inches in depth shall constitute failure of this test. Sufficient measurements shall be taken to determine the in place quantity of material compacted. The above procedure shall be repeated for a total of 3 times for each type of soil. The average compacted cubic yards shall be determined. After all compaction measurements have been computed, the compactor shall continue to compact soils at the 1500 cubic yard per hour rate to verify conformance.

4.5.2.2.1 Failure criteria. An average compaction rate of less than the compacted cubic yards per hour specified in 3.1.3 and failure to achieve full depth material density or minimum compacted fill layer thickness as specified in 4.5.2.2 for each test shall constitute failure of this test.
