Compaction test vs density test
Did you know?
WebCompaction is the process by which the volume of air in an HMA mixture is reduced by using external forces to reorient the constituent aggregate particles into a more closely spaced arrangement. This reduction of air volume produces a corresponding increase in HMA density (Roberts et al., 1996 [1] ). WebApr 21, 2024 · Assessing the level of compaction of sub-surface soils can be essential to designing and validating compaction, particularly those subject to transient or cycling loads. A perfect example is roadways. ... One alternative to soil extraction is Nuclear Density testing. Nuclear Density testing requires a radiation source such as Cesium or Radium.
