High Quality Soil CBR Test Machine

It is suitable for all kinds of soils and mixtures (soil with a grain diameter of less than 40mm) to be compacted in the specified test cylinder mold to carry out the bearing ratio test to determine the bearing capacity of the designed pavement, pavement base, subbase and roadbed material layer. It is one of the necessary instruments for geotechnical testing. The instrument is composed of the main engine, the force ring, the penetration rod, etc. (the loading plate, the porous permeable plate, the dial indicator, etc. belong to the 9-piece set of CBR accessories). The instrument has the characteristics of small size, small output and convenient operation.

In the lab, soil specimens with specific moisture contents are compacted into molds. Sample preparation prior to testing may include soaking and the addition of surcharge weights to the molded specimens. The penetration test is carried out in a Load Frame outfitted with a Penetration Piston and other CBR test components.

CBR Field Tests measure the strength of in-place soils and base course materials, providing valuable information to pavement designers while maintaining ASTM D1883 and AASHTO T 193 standards. Field tests are run by forcing a Penetration Piston into the soil with a gear-driven Jack at the test site and comparing the depth of penetration to the load. Typically, the Jack is braced against a heavy piece of equipment used for a reaction load, such as a loaded dump truck.

The Florida Limerock Bearing Ratio (LBR) FM 5-515 laboratory test was developed to evaluate limerock and other soils used for the base, subgrade, and embankment materials typically found in Florida. This test method shares much of the same equipment and procedures used with the laboratory CBR test.

Gilson offers a complete line of laboratory and field equipment for California Bearing Ratio (CBR) testing and laboratory equipment for the Florida Limerock Bearing Ratio (LBR) test.

• CBR Lab Equipment includes customizable Load Frames fitted with components to perform CBR or LBR Tests. Frames can also be outfitted with a variety of components for other soil testing applications. In addition, our selection of CBR lab testing products includes Molds, Spacer Discs, Swell Plates, Surcharge Weights, and other accessories to test laboratory-prepared soil samples.
• CBR Field Equipment consists of CBR Field Jacks, Load Rings, Surcharge Plates, and Penetration Pistons to provide penetration data from in-situ field tests.
•  LBR Equipment is similar to CBR laboratory test equipment but uses unique Compaction Molds and Spacer Discs.
