高等级公路沥青路面结构设计参数的统计分析研究

The Research and Analysis on Variablity of Asphalt Pavement Structure Design Parameters of High-grade Highway

通过在陕西省几条高等级公路上选择一些试验路段，进行现场试验和随机取样进行室内试验，获得了沥青路面结构设计参数的大量试验数据，经过数理统计分析，得出了主要设计参数的变异水平和概率分布规律。

On the basis of a host of data of asphalt pavement structure design parameters obtained by site tests and laboratory tests, this papaer calculates out the variable coefficients and probability models of the parameters with mathematical statistics.
