路面行驶质量水平评价标准方法研究

Method Research on Evaluation Standard of Pavement Ride Quality

在回顾已有的国际平整度指数作为路面评价标准的基础上,结合上海市沥青路面行驶质量水平评价标准确定实例,提出了一种新的基于国际平整度指数路面行驶质量评价标准确定方法.选择典型沥青路面,用精密水准仪测量路段的断面高程,计算出各路段的国际平整度指数与舒适度指数,通过最小二乘法建立国际平整度指数与舒适度指数之间的回归方程,由舒适度指数与路面行驶质量水平的关系,建立以国际平整度指数作为沥青路面行驶质量水平的评价标准.

With the review of the previous pavement evaluation standard based on IRI （international roughness index）, a new method is proposed. Profiles of a series of representation asphalt pavement were measured by rod and precision level. IRI and ride number （RN） of those profiles were calculated by programs. The regression equation between IRI and RN was obtained by least square method. Evaluation standard of Shanghai asphalt pavement ride quality on the basis of IRI was established through the relationship between RN and pavement ride quality.
