Compaction was aaomplishcd by laying fill in thin horizontal layers and compacting with a com- <br />pactor and scrapers. Standard Proctor densities were determined in our lab using methods outlined in <br />AASHO Standard Method T99~i1. Compacted density and moisture content of the placed fill material was <br />monitored usinga nuclear density probe to ensure adequate compaction. <br />er ~ '~~ <br />Roger .Fish <br />Colorado PE No. 26063 <br />~/9 ~ <br />Date <br />c'~O.~~yrrttr~~,~s <br />dv <br />•o <br />26063 <br />~; <br />~~iO~fS'••....••~~ <br />4y4.,S~CNRL EN <br />RWFhb BAl <br />IPERMI7\DAMCFRTt1 <br />
