CBR Test

CMTL provides comprehensive soil stabilisation testing to establish suitability for stabilisation or reuse. CBR tests and plate bearing tests are just some of the methods we use on site to analyse suitability for its intended purpose.

CBR Testing

California Bearing Ratio Testing (CBR)

The CBR test is used as a strength test which to determine the thickness of materials needed for the proposed road construction.

The CBR test measures the pressure required to penetrate a soil sample, compared to the pressure needed to penetrate a standard crushed rock substance. The harder the surface, the higher the CBR value will be. Typically, a value of 2% equates to clay-like substance, while some sands can have a CBR value of 10%.

Plate Bearing Test
