Field Procedure for Determining the Test Maximum Density of Asphalt Concrete

M. L. Alexander

A procedure for determining the test maximum density of asphalt concrete in a field laboratory was developed and then tried on several paving projects. This test maximum density is required to determine the in-situ relative compaction of asphalt concrete per California Test 375. The procedure involves the use of a hydraulic jack to apply a 133 500 N static load for compaction in lieu of using a kneading compactor. Although the test maximum densities achieved by this static loading are normally lower than the values determined using a kneading compactor, a correlation factor can be determined and applied. In most cases, the test results can be available within two hours of obtaining a sample of the material.
