Project Specifications and compacted to a minimum of 90 percent compaction relative to ASTM D1557. Maximum Density/Optimum Moisture Content Testing (ASTM D 1557) will be conducted at a frequency of at least one (1) test per every 5,000 c.y. or as deemed necessary by the Engineer. Field compaction testing will be conducted by nuclear gauge or sand cone methods at a minimum frequency of one (1) test per 1,000 c.y. placed. 5.3 EXCAVATION AND PROCESSING Selectively excavated on-site soils or approved import materials shall be screened (if necessary), to exclude particles in excess of one (1) -inch within one (T) -foot of the geosynthetics and three (3) -inches throughout the remainder of the fill. Fill soils will be dried, and/or moisture conditioned as necessary until uniformly blended material characteristics and moisture condition are attained. Processed, blended and moisture conditioned materials will then be used as engineered fill. No soils other than those approved by the Geotechnical CQA Consultant are to be usedfor the project. 5.4 ACCEPTANCE CRITERIA 5.4.1 GENERAL Where test results indicate that the lift thickness, maximum particle size, homogeneity of material, moisture content or density of any portion of the work is below the project requirements, that particular portion shall be reworked or replaced until the required condition has been attained and the resulting product meets or exceeds the requirements of the Project Specifications. Tho additional fill shall be placed over an area until the existing fill has been tested horizontally and vertically and determined by the Geotechnical CQA Monitor to meet the` Project Earthwork Specifications. The area to be reworked will be verified by survey if in the opinion of the Geotechnical CQA Monitor conditions warrant. 5.4.2 MOISTURE CONTENT AND DENSITY If in the opinion of the Geotechnical CQA Officer or designated representative, engineered fill materials which have been placed and/or are ready to be placed, do not visually have a uniform and homogeneous moisture content throughout the material in question, these materials will be removed, without testing, and will be reprocessed and/or reworked until, in the opinion of the Geotechnical CQA Officer or his/her designated representative, they meet the Project Specifications. For all compacted fill materials placed, if test results indicate a relative dry density of less than that required or a moisture content outside the specified limits, then the area will be considered inadequate and will be reworked or replaced. Any reworked areas will be retested by the Geotechnical CQA Monitor to verify the reworked area meets the density and moisture content requirements. -11- CA2001-048TINAL COV ER CQA.DOCA08/20/01 GeoLogic Associates
