What is CBR Testing?

Also known as a Plate Load Test this is a procedure used to evaluate the sub-grade ground strength in the design and construction of roads and pavements.. It is 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, and that is why the procedure is known as 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.

Our CBR Testing services evaluate how much force is needed to penetrate a particular section of soil regardless of its composition. This is done with the help of a standard penetration plunger. Once the pressure is determined, it is divided by the amount of force required to achieve similar penetration on standard soil. The results are what is known as the CBR value.

Apparatus & Equipment Used

We make use of high-quality equipment to ensure no errors are made during the whole procedure. Some of the apparatus we use includes Dial gauges and Spacer discs. We also use Surcharge Weights, Loading Machines, and most importantly, the Penetration Plunger. Each of these components will ensure successful penetration of the site’s ground and provide accurate calibration to complete the test successfully.

Our CBR Testing services provide accurate and detailed the CBR values. These values allow construction companies to determine how stable the ground is and whether it will be able to hold the intended project. This will prevent further issues once the project is underway.

When should CBR Testing be undertaken?

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.
