What is CBR Testing?
This is a procedure used to evaluate the sub-grade ground strength in the design and construction of roads and pavements. It’s imperative that engineers and construction companies know the penetration resistance of the soil. In order to determine how strong the ground, base course, and the substrates are before undertaking a construction project. The California Department of transport invented the test, naming it the California Bearing Ratio test. Commonly referred to as the CBR Testing, CBR Testing is specified in BS1377: Part 9: 1990: Soils for civil engineering purposes.

CBR Testing is a test to evaluate the amount of force needed to penetrate the soils using a circular plate.
Digital dial indicators measure the settlement of the plate in increments of .25mm upto 1.5mm in order to create a graph and plot the results, this will calculate the CBR value and “K” value engineers require to evaluate and implement their design.
Highly recommended
I have used STS on various schemes over the last few years and have always found them to be professional, give great service and will go out of their way to accommodate should difficult situations arise. I would recommend highly to anyone to use their services.

In general, the process should be undertaken whenever you want to find out how stable is the subsoil and the base material of a particular area.
This then provides the information required to determine the highway thickness, the suitable road pavement designs, parking designs, loading designs, along with how to establish a temporary foundation.
