For determining the compaction rate of soil, admixture, roadbed or roadbed consisting of soil, sand or lime, a plate test is performed on site. The goal of a plate test is to measure the slump of a rigid plate with centric load. Because of the limited penetration depth, a plate test can only give information on the compaction of a limited soil thickness. Therefore, plate tests are applied generally in road construction, with landfills or for data acquisition for slab calibration.
The standard plate test device consists:
