Hi everyone. My question concerns the backfill on our pipe trenches. Our Contractors always say that the reason they are not utilizing the native material as backfill to our trenches is the problem with rain. They are saying that when their compacted backfill is exposed to rain (I expect continous pouring), it will never pass the field density test. In our specification, allowed native material must fall between class A-1 to A-3 of AASHTO soil classification. Considering such backfill material, we go back to the question "does rain hurt compaction?"
