CBR TEST PROCEDURE & ITS SIGNIFICANCE

Описание к видео CBR TEST PROCEDURE & ITS SIGNIFICANCE

The California Bearing Ratio test commonly known as CBR is used to determine the strength of the subgrade materials being used in the flexible pavement. The design of flexible pavement is based on the strength of the materials used in subgrade in terms of CBR. For a given traffic load the crust thickness will be more if the CBR of the soil is less and the crust thickness will be less if the CBR of the subgrade is high. Therefore it is very important for the field engineers to test the CBR of the subgrade accurately to avoid any defects is future due to loading.
