The average CBR value of three test specimens is reported to the first decimal place, as the GBR value of the test specimen. If the maximum variation' iii the CBR values of these specimens exceeds specified limits (3% for CB up to 10% to 5% for CBR 10 to 30% and 10% for CBR 30-60%), then the design CBR should be the average of at least six specimens.

Explanation:
CBR (California Bearing Ratio) test is used to determine the strength of the subgrade soil and the base course material for designing the pavement thickness. The test involves penetrating a plunger into the soil at a constant rate of penetration and measuring the force required to penetrate the soil at different depths. The ratio of the force required to penetrate the soil to the force required to penetrate a standard crushed rock material at the same depth is known as the CBR value.
If the CBR value obtained at 5 mm penetration is higher than that at 2.5 mm, then the test is repeated for checking. The aim of the repeated test is to ensure the consistency and accuracy of the CBR value. If the check test reveals a similar trend, then the CBR value is to be reported as the higher value obtained at 5 mm penetration.
The reason for reporting the higher value obtained at 5 mm penetration is that the CBR value at 5 mm penetration is considered more critical than that at 2.5 mm penetration. This is because the thickness of the asphalt layer in a pavement design is usually greater than 5 mm. Therefore, the CBR value at 5 mm penetration is more relevant for designing the pavement thickness.
To summarize:
- CBR test is used to determine the strength of the subgrade soil and the base course material for designing the pavement thickness.
- If the CBR value obtained at 5 mm penetration is higher than that at 2.5 mm, then the test is repeated for checking.
- If the check test reveals a similar trend, then the CBR value is to be reported as the higher value obtained at 5 mm penetration.
- The CBR value at 5 mm penetration is considered more critical than that at 2.5 mm penetration for designing the pavement thickness.
