Soils. <br />I. ASTM D 4643 - Test Method for Determination of Water (Moisture) Content of Soil <br />by the Microwave Oven Method. <br />PART 2: PRODUCTS <br />2.01 FILL MATERIALS <br />A. Fill materials shall consist of Cushion Material, Squeegee Material, and Random Fill <br />as specified in Section 02205. <br />PART 3: EXECUTION <br />3.01 PREPARATION <br />A. Prepare subgrade according to Section 02211. <br />B. Do not place fill until subgrade has been tested and approved by the Owner. <br />3.02 FILL PLACEMENT <br />A. Do not place frozen material as fill, and do not place fill on frozen ground. <br />B. Imported material must be tested for compliance with the Specifications and the <br />results approved by the Owner prior to the material being delivered to the site. <br />C. Fill shall be placed to the designed lines and grades and according to these <br />Specifications. <br />D. If, in the opinion of the Owner, the surface of the prepared foundation or the rolled <br />surface of any layer of the fill in place is too wet for proper compaction of the layer <br />of fill material to be placed thereon, it shall be removed and allowed to dry or shall <br />be worked with discs, scarifier, or other equipment to reduce the moisture content to <br />the required amount, and then compacted before the next layer of fill material is <br />placed. <br />E. Fill shall be placed only after subgrades below fills have been adequately compacted <br />and approved by the Owner. <br />F. All fill materials shall be moisture- conditioned prior to applying compactive effort. <br />Moisture- conditioning may be performed to fill material either in the borrow area or <br />at the fill site or in both areas as directed by the Owner. <br />G. When material is too dry for proper compaction and/or is below the minimum <br />moisture content specified, the Owner shall spray water on the fill and work the <br />moisture into the fill by discing or scarifying or other approved means until a <br />uniform distribution of moisture is obtained. <br />H. The relative compaction of fill materials shall be tested in place to check compliance <br />to the Specifications. Relative compaction of soil materials, with less than 30 <br />percent rock greater than the 3/4 -inch mesh size, is the ratio of the in -place dry <br />density of the constructed fill to the maximum laboratory dry density determined by <br />Revision A 02223 -2 January 2008 <br />t`O743I745M0010 I LLnOAApp 6T¢Inpad02723 - Fi1b.g Roy AI OOC <br />
