Faulting Evaluation Criteria of Cement Concrete Pavement

Abstract:

Based on a case study of the joint faulting evaluation criteria in Chongqing, a new method was proposed for rating the joint faulting with a consideration of the level of ride quality. Two representative cement concrete pavement sections were chosen, then the joint faulting values and localized roughness index（LRI） of those pavement sections were detected. The relationship between joint faulting and LRI was revealed by the regression analysis. Then the joint faulting evaluation criteria were obtained based on the relationship between localized roughness and ride quality.
