ANS:C - character of the road making materials

California Bearing Ratio (CBR) test gives specifications of road-making materials.

California Bearing Ratio (CBR) test is a method of classifying and evaluating soil-subgrade and base course materials for flexible pavements.

CBR test, an empirical test, has been used to determine the material properties for pavement design.

This test measures the strength of the material and is not a true representation of the resilient modulus.
