The C.B.R. Method is used for finding the relative bearing ration and expansion characteristics of soil of base, sub base and sub grade for the design of roads, pavements and runways.

Standard: IS: 2720 (Part XVI)

Test can be made on all types of soils including sand, gravel, crushed stone etc. C.B.R. test is used extensively for selection of materials and control of sub-grades.

The procedure of test is very simple. A 50mm dia penetration piston is forced in the test soil and loads required for the penetration to penetrate different depth are recorded by means of a proving ring fixed to the penetration piston assembly and a dial gauge. Both Laboratory C.B.R. and field C.B.R. apparatus are available.

Available in manually operated or motorized control models. Motorized control model consists of load frame with 1.25 mm/min rate of strain and can be operated on 230V AC.

Standard: IS: 1205 - 1985, IP: 58/63

More About Marshall Stability Test Apparatus : This apparatus is used for test, which is applicable to hot mix designs using bitumen and aggregates up to a maximum size of 25 mm. In this method, the resistance to plastic deformation of cylindrical specimen of bituminous mixture is measured when the same is loaded at periphery at 5 cm per min. This test procedure is used in designing and evaluating bituminous paving mixes. The test procedure is extensively used in routine test programs for paving jobs. There are two major features of the Marshall method of designing mixes namely, a) density – voids analysis b) Stability – flow tests. The Marshall stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60ºC. The flow value is deformation the Marshall Test specimen under goes during the loading up to the maximum load, 0.25 mm units. In this test and attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.
