Methods of testing soils for engineering purposes, Method 5.7.1: Soil compaction and density tests - Compaction control test - Hilf density ratio and Hilf moisture variation (rapid method)
工程用土壤试验方法 方法5.7.1:土壤压实和密度试验-压实控制试验-Hilf密度比和Hilf水分变化(快速法)
This Standard sets out a rapid method for determining compaction control parameters for
soils. The method involves relating converted wet density (CWD) of the laboratory compacted soil to added moisture (Z) without the need to determine moisture content.
