The upper sample will be referred to <br />as Proctor Sample Number 9P for this project and the lower sample will be referred to as Proctor Sample Number <br />10P. <br />Remarks: <br />The material tested appeared to not be adequately mixed at the time of initial testing, which led to low compaction <br />results. The contractor then excavated and re-mixed the lift before recompacting. Upon re-tes#ing the materials <br />appeared to be properly compacted and uniformly moistened. <br />The material tested generally met the project specifications for compaction and moisture content. <br />Please refer to the attached sheet for results of todays testing. <br />Verbal Discussions: <br />Dusty Wiseman of Anson Excavating was notified of today's test results. <br />Att.
