Proper earthwork compaction is a critically important factor for satisfactory performance of highways, dam,… . A number of new and proven devices, e.g., the light weight deflectometer (LWD), Clegg Impact Hammer and the dynamic cone penetrometer (DCP), are capable of more rapid inspection of materials with large size aggregates to depths of 24 inches or more (for DCP).In our research we investigate the advantage or limitation of application these device on earth dam core material, specifically cohesive soil. Does anybody has any experience in this field to help us? Secondly Does anybody has data about light DCP (ASTM) test on clay or correlations equation between this device and Clegg Hammer?
