CBR of 8% and has good drainage characteristics with coefficient of permeability as 6.3 * 10-2. From the compaction curve it can be seen that sand attained a maximum dry density of 1.82 g/ccat optimum moisture content of 6%.Comparing the above characteristics of crusher dust with sand, crusher dust attained higher densities with wide variation of

The harder the surface, the higher the CBR value. Typically, a value of 2% equates to clay, while some sands may have a CBR value of 10%.

The California Bearing Ratio (CBR) test is a simple strength test that compares the bearing capacity of a material with that of a well-graded crushed stone (thus, a high quality crushed stone material should have a CBR @ 100%).It is primarily intended for, but not limited to, evaluating the strength of cohesive materials having maximum particle sizes less than 19 mm (0.75 in.) (AASHTO, 2000{{1}}).

What are the typical CBR values? The harder the material, the higher the CBR value. A CBR value of 2% is usually found for clay, high-quality sub-base will have CBR values between 80% and 100%, and some sands may have values around 10%. The CBR testing can be applied to soils with a maximum particle size of 20 mm.

year to year. The CBR test results are relatively uniform from 1978 through 1981. There was a dramatic increase in CBR values in 1982. This increase is consistent with the addition of a third crusher to the plant operationi the increase in the quantity of crushed particles would explain the increase in

CBR value is expressed as a percentage of the actual load causing the penetrations of 2.5 mm or 5.0 mm to the standard loads mentioned above. Therefore, • The greatest value calculated for penetrations at 2.5mm and 5.0mm will be recorded as the CBR. When the graph begins to concave up this is likely due to surface irregularities and so the ...

The load values on standard crushed stones are 1,370 kgf (13.44 kN) and 2,055 kgf (20.15 kN) at 2.5 mm and 5.0 mm penetrations respectively. The CBR value is expressed as a percentage of the actual load causing the penetrations of 2.5 mm or 5.0 mm to the standard loads mentioned above. The CBR can therefore be mathematically expressed as:

Divide the crusher-run course surrounding the inspection chamber into two layers for compaction. Keep the water content of the first layer at the optimal condition, and use the multi-contact tool to compact the same area three times (Photo 4). The thickness after compaction shall be 100 mm (160 mm for the entire crusher-run course).

California Bearing Ratio (CBR) and Limerock Bearing Ratio (LBR) tests yield relative strengths of soils and base course materials based on penetration resistance. CBR values can be determined under laboratory or field conditions, while the LBR test is performed only in the laboratory.

The CBR test is one of the most commonly used methods to evaluate the strength of a sub grade soil, sub base, and base course material for design of thickness for highways and airfield pavement.. The California bearing ratio test is penetration test meant for the evaluation of subgrade strength of roads and pavements. The results obtained by these tests are used with the empirical curves to ...
