OLD RIVER GOLF COURSE <br /> Page No. 10 <br /> (4) Required Densities <br /> The dry density of the compacted earth fill shall be at least <br /> 90 percent of the maximum dry density obtainable in the ASTM <br /> D1557 Compaction Test. The value of the optimum moisture <br /> content and maximum dry density will be determined by the <br /> engineer and this information supplied to the contractor. <br /> (5) Seasonal Limits <br /> No fill shall be placed during weather conditions which will <br /> alter the moisture content of the fill materials sufficiently <br /> to make adequate compaction impossible. After placing <br /> operations have been stopped because of adverse weather <br /> conditions, no additional fill material shall be placed until <br /> the last layer compacted has been checked and found to be <br /> compacted to the specified densities. <br /> (6 ) Control of Compaction <br /> The density of the upper 6 inches of subgrade and of each <br /> layer of fill shall be checked by the engineer after each <br /> layer has been compacted, Field density test shall be used to <br /> check the compaction of the fill materials. Sufficient tests <br /> shall be made on each layer by the engineer to assure adequate <br /> compaction throughout the entire area. If the dry densities <br /> are not satisfactory, the contractor will be required to <br /> increase the weight of the roller, the number of passes of the <br /> roller, or manipulate the moisture content as required to <br /> produce the specified densities. <br /> P pERg h <br /> s » <br /> z r <br /> _ c � <br /> �ssoc� <br />
