California Bearing Ratio Test Apparatus, Field TypeIS: 2720 (Part 31)The use of the in-situ CBR apparatus on large road construction projects has increased considerably in recent years. This apparatus, mounted on a rolled steel joist cantilevered from the back of the truck or fitted to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiently. This method of testing in-situ, using piston penetration, is useful for determining the load carrying capacity in the field, when the in-place density and water contents are such that the degree of saturation is 80 % or greater, when the material is coarse grained and cohesion less so that it is not affected by changes in the water content and when the material has been in place.It consists of:
Loading Jackwith U-bracket, capacity 50 kN (5, 000 kgf). This is specially designed for use with Field CBR test apparatus. It consists of a hand operated, two speed, screw jack fitted with a U-bracket. A hexagonal adapter is provided to fix a proving ring. A thrust bar, which passes through the U-bracket, is screwed on to a proving ring (supplied at extra cost) which protects the proving ring when the loading is eccentric.
