I'm trying to determine a correlation between Standard and Modiified Proctors. Here's my problem. Small strip mall in silty clay over limestone and sinkholes opened during a recent 2-inch storm.The GC is using available material for compaction and recent moisture content hit 23%. (I did not perform the lab work and don't have a copy of the results yet.) I specified a Modified Proctor at 100% density. The best results the GC is getting is 85% for the Modified but 105% for the Standard. He wants to switch to the Standard. A basic walk thru after the 2-inch rain does not indicate any significant loss in compaction already in place. None of my reference books(Bowles, Das & Hough) really discuss ASTM procedures in depth.
