In that situation have to replace the retained amount with an. Take sample for determination of moisture content. The test is carried out on natural. If all material passes through the sieve, we can use all of it for the test. Weigh of empty mould add water to the first specimen (compact it in five layer by giving 10 blows per layer) after compaction, remove the collar and level the surface. The cbr test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. 4.procedure preparation of test specimen: Normally 3 specimens each of about 7 kg must be compacted so that their compacted densities range from 95% to 100% generally with 10, 30 and 65 blows.

Weigh of empty mould add water to the first specimen (compact it in five layer by giving 10 blows per layer) after compaction, remove the collar and level the surface.

The cbr test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. The test is carried out on natural. Call for a free quote 0333 5670 754. A cbr of 3 may represent tilled farmland, a cbr of 4.75 the turf or. If all material passes through the sieve, we can use all of it for the test. Extensive use of the california bearing ratio over a long period and information gained from field correlations have established its reliability for pavement design. Normally 3 specimens each of about 7 kg must be compacted so that their compacted densities range from 95% to 100% generally with 10, 30 and 65 blows.

Cbr Test Procedure. Detail cbr test procedure is described below. The harder the surface, the higher the rating. 4.procedure preparation of test specimen: The test procedure should strictly adhere if a high degree of reproducibility is desired.

The cbr test is carried out on soils with a maximum particle size of 20mm. Take sample for determination of moisture content. 4.procedure preparation of test specimen:

A ¾ in (19 mm) sieve is used to sieve the soil specimen. Normally 3 specimens each of about 7 kg must be compacted so that their compacted densities range from 95% to 100% generally with 10, 30 and 65 blows. The test procedure should strictly adhere if a high degree of reproducibility is desired.

The harder the surface, the higher will be the cbr value.
