California Bearing Ratio Apparatus

We are reckoned as the most established manufacturer, exporter and supplier of California Bearing Ratio Apparatus in Kolhapur, India. They are very useful in finding the expansion characteristics and relative bearing ratio under known surcharge weights of the base, sub-base and the sub-grade soils that are used for the design of roads, pavements and runways. This test is used widely to ensure the quality of the soils which has led to high demand for the product. They are reliable and provide the best result every time. The apparatus can be availed from us at leading market prices.
