Design of Flexible Pavement by CBR Method

This study explores the dominant method for designing flexible pavements: the California Bearing Ratio (CBR) method.The CBR method directly relates a subgrade's strength, measured by a standardized CBR test, to the required pavement thickness.A higher CBR value indicates a stronger subgrade, necessitating a less substantial pavement structure.To assess the effectiveness and potential discrepancies of the CBR method, this investigation will apply it to a specific pavement design scenario.This scenario will encompass a representative traffic volume and subgrade characteristics.A meticulous comparison of the resulting pavement thicknesses obtained from the CBR method will be conducted.For instance, the CBR method might be preferable for projects with weak subgrades or heavy traffic loads, as it directly accounts for the subgrade's bearing capacity.
