Poor CBR tests in crushed rock gravel - Geotechnical ...

15.02.2005  I had two CBR tests run in a crushed rock gravel, gap-graded with about 20 percent fines. It was produced by a rock crusher on-site, and acts a lot like screenings. The CBR results are a concave shape for the entire curve up to 0.5 inch deflection. ASTM says to run the tests again, however, I have two tests of similar shape, so I think a rerun will be similar. The CBR results range from 4 to 5 ...

CBR Test Southern Testing

How is a CBR Test performed? The CBR test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. The measured pressure is then divided by the pressure required to achieve an equal penetration on a standard crushed rock material. The harder the surface, the higher the CBR value. Typically, a value of 2% equates to clay, while some sands may

4 Results: California Bearing Ratio (CBR)

CBR-value is a familiar indicator test used to evaluate the strength of soils for these applications (Nicholson et al., 1994). CBR-test was conducted to characterize the strength and the bearing capacity of the three studied soils and their mixtures with lime, fly ash, and lime/fly ash. The test procedures and the preparation of the specimens were achieved according to the procedures in ...

SOILS Proficiency Testing - PTA

The California Bearing Ratio (CBR) is a penetration test for evaluation of the mechanical strength of road sub grades and base courses. It was developed by the California Department of Transportation in the 1930’s. The CBR is used for measuring the load-bearing capacity for new pathways, road and airstrips or for soils already under paved areas.

Take the average of three test specimens as the CBR value of the test. Generally, the CBR value at 2.50mm penetration will be greater than that at 5.00mm penetration and in such case take the value at 2.50mm as the CBR value. If the CBR value corresponding to a penetration of 5.00mm exceeds that of 2.50mm,repeat the test.
