MOORE & TABER NORTHERN CALIFORNIA <br /> C O N S U L T i N O ENGINEERS A N D G EOL O O 1 5 T S <br /> GUIDE SPECIFICATION-CONTROLLED FILL <br /> C. Placement of Fill <br /> 1. Fill material shall be spread in uniform layers not exceed- <br /> ing 6-inches compacted thickness. Water shall be added to <br /> the fill or the fill allowed to dry as necessary to obtain <br /> fill moisture content at which compaction as specified can <br /> be achieved. <br /> 2. Each layer of fill shall be compacted to not less than 90% <br /> of maximum density achieved by ASTM D 1557 unless otherwise <br /> specified. Compaction shall be by sheepsfoot rollers, <br /> multiple-wheel pneumatic rollers or other acceptable rollers <br /> of such design that the fill can be compacted as specified. <br /> 3. If work has been interrupted by weather, scheduling or for <br /> any other reason, the Soils Engineer shall be notified by <br /> the superintendent of grading at least 24 hours prior to the <br /> intended resumption of grading. <br /> D. Supervision and Control <br /> 1. Field density tests shall be made of each layer of fill. <br /> Sufficient tests shall be made to assure that the required <br /> compaction has been achieved throughout the fill. When <br /> tests indicate that the specified compaction has not been <br /> achieved, that portion of the fill shall be re-worked until <br /> the required density has been attained. <br /> 2. Preparation of fill foundation and placement of fill shall be <br /> supervised by the Soils Engineer so that he can render a pro- <br /> fessional opinion on the conformance of the completed fill to <br /> the specifications. <br /> 12/15/70 Page 2 of 2 pages <br />
