A compaction test is a soil quality test used to assess the level of compaction which can occur in the soil on a site. The Plate Load Test basically consists of loading a steel plate placed at the foundation level and recording the settlements corresponding to each load increment. California Bearing Ratio (CBR) Calculation is one of the most complicated calculation in civil engineering tests. Plate Load testing is usually used for the verification of the bearing capacity of the land of the substrate, of the foundation layer and the base layer of the flooring, although it is not uncommon to its use to investigate the bearing capacity of the soil surface or to the state compaction of granular materials and road surfaces.
