Web1 jan. 2011 · The ASTM Standard Test Methods used for determining compaction characteristics of soil are D698, D1557, D558, D4253, and D4254. These test methods are performed in the laboratory on samples obtained from the borrow area and are used to establish specimen compaction requirements for engineering property testing. The California Department of Transportation has developed a similar test, California Test 216, which measures the maximum wet density, and controls the compactive effort based on the length (in fact the height) of the test sample and not on its volume. The primary advantage of this test is that maximum density test results are available sooner, as evaporation of the compacted sample is not necessary.
