水泥混凝土路面错台分级方法

Faulting Evaluation Criteria of Cement Concrete Pavement

摘要:

结合重庆市水泥混凝土路面错台病害评价标准确定实例提出了一种基于路面行驶质量水平的错台量分级方法.首先选择2个典型的水泥混凝土路段，详细检测选定路段的错台量和局部平整度值（LRI）；通过数值分析建立错台量与局部平整度指标之间的相关关系模型；最终由局部平整度与行驶质量水平间的关系建立基于行驶质量水平的错台量分级标准.

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.
