The use of this <br /> method compaction technique was necessary as the select structural fill material contained <br /> more than 30 percent rock above the 3/4-inch sieve, classifying it as a rock fill. It was found <br /> that in conjunction with the specified lift size of 12 inches, four passes of the BW211 Bomag <br /> roller would be sufficient for compaction in the method specification. <br /> Select structural fill transported the previous day was compacted by a BW211 Bomag roller. <br /> Additional select structural fill was transported and dumped by a Volvo A4OF articulated dump <br /> truck (approximately 25 CY per load). The fill was spread using a loader to a loose thickness of <br /> 12 inches. The subgrade along the side slopes and select structural fill were moisture <br /> conditioned where necessary and then compacted. <br /> Page 1 <br />
