CBR value is determined by penetrating this 50 mm cylindrical plunger into the soil sample at the rate of 1.25 mm/minute and load at 2.5 mm penetration and 5.0 mm penetration is noted by proving ring. CBR value is expressed as a percentage of standard load value which is obtained after numerous tests on coarse aggregates.

The CBR test is used for determining the sub-grade strength value of pavements and roads. The results obtained from the CBR test are used with the Imperial curves for the determination of the thickness of pavement and various component layers of pavement. California bearing ratio value used as an index of soil strength and its bearing capacity.
Details 
46.4.1 General. The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of road subgrades and base courses. The test should be performed in accordance with BS 1377-9:1990, 4.3. NOTE 1 The test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area.

In a Plate Loading Test, comprehensive stress will be applied to the pavement or soil layer through rigid plates that are relatively large in size and then the deflections will be measured for different stress values. This deflection level is limited to a low value and will be in the 1.25mm-5mm order. The site investigations for many projects ...

Problem 3: CBR Test Data taken during a CBR test is presented below What is the CBR of this soil? Comment on the suitability of the soil for a subgrade. The diameter of the penetration piston is about 2 inches leading to a piston area of about 3 in2. You can find the AASHTO standard for the CBR test in the C431d21 site under the folder ...

CBR testing is used in the design of flexible pavements and since its development, it has been widely adopted internationally. CBR testing method. The CBR testing method consists of forcing a 50mm cylindrical plunger to penetrate the test material at a rate of 1.25mm per minute. The load at 2.5mm and 5mm penetration are recorded.

(a) CBR test set up (b) Field plate load test set up. Figure 1. Figure of CBR and PLT set up. The CBR test can also be used to get the curve of the load–settlement of the soil in the field which is more or less similar to the plate load test objective. By this idea, the value of k. s. can also be obtained from the CBR test as de-scribed below.

msa (million standard axles), the CBR value should not be less than 20%. For cumulative traffic greater than 2 msa (million standard axles), the CBR value should not be less than 30%. Note: CBR test is performed for both soaked and unsoaked soil specimen. Usually, the unsoaked CBR value will be greater than the CBR value for soaked condition.
