Static Plate Load VSS

 

Plate load test with the use of VSS plate  is designed to determine density of fill, bearing capacity and density of substratum and some types of substructures (like road foundations).  This test allows to establish the values of primary E1 and secondary modulus of elasticity E2 and effective strain Io. The test characterizes the superficial substratum to the depth of 30-50 cm, this is way it is often used for linear constructions, especially for roads.
The test consists in measurement of soil settlement under  the plate while loading with the use of counterweight.
