<br />' <br /> The gradation shall be as follows: <br />' U.S. Standard Sieve Percent Passing <br /> or Screen Opening_ By Wei hg t <br />' 1 inch 100 <br /> 3/4 inch 90-100 <br /> No. 4 35-65 <br />' No. 15 15-40 <br /> No. 200 2-10 <br /> <br /> In addition, the fines (minus No. 200 sieve size) shall be nonplastic. <br />' <br /> 6.4 Moisture Control <br /> <br /> 6.4.1 General <br />During compaction operations, the materials being placed and the surface of [he fill shall be <br />maintained within the moisture content range required to permit proper cornpac[ion to the <br />' specified density with the equipment being used. The moisture content of the fil: materials prior <br />to and during compaction shall be unifotm throughout each layer of the material. <br />' If material spread on the fill is drier than specified for compaction, the Contractor shall spray <br />water on each layer of the fill and work the moismre into the fill by harrowing or other <br />approved means until a uniform distribution of moisture at the proper contt:nt is obtained. <br />Material spread on the fill that is too wet for proper compaction shall be removed or it may be <br />left on the fill and permitted to dry, assisted by discing and harrowing as necessary, until the <br />' moisture content is reduced to an amount suitable for obtaining the specified percent of <br />compaction. If material is left on the fill to dry, no material may be placed over the wet material <br />until it has been dried, reworked, and properly compacted. <br />Mixing of wet and dry material to obtain the proper moisture content shall not be done. Placing <br />' mixed material shall only be done after the material has cured and a uniform distribution of the <br />moisture content has been achieved and approved by the Engineer. <br />t <br /> <br />_~4_ <br /> <br />
