Comparisons of Vibrated Density and Standard Compaction Tests on Sands with Fines,

摘要

Generally,two laboratory test methods,relative density and standard compaction (impact),are used in establishing density requirements for the placement of embankment materials. The relative density test method is specified for cohesionless soils,generally when fines do not constitute more than 5-12percent by weight,while the standard compaction test is for cohesive soils. However,for sandy soils containing varying amounts of fines,selection is often based upon the test method considered appropriate to the material. This study was an investigation of various criteria for assisting in compaction test method selection for cohesionless soils with fines.
