Measuring the Effect of Mixed Grading on the Maximum Dry Density of Sands

摘要

During cut and fill operations, compaction using sands from different sources may be carried out. The resulting mixed sand will have different compaction characteristics than those of the parent sands. An increase in dry density will result as the grading moves towards more ideal characteristics for dense packing. Laboratory compaction tests using pluviation and the vi- brating hammer method have been carried out to measure this in- crease in dry density.
