摘要：

Authors brought forward an evaluation method of surface segregation of asphalt pavement from the point of view of statistics based on the practical experiences from lots of engineering projects. Firstly, information about surface configuration depth of asphalt pavement was got by the laser texture measurer, and it was analyzed based on the statistics. Then a four-dimensional chart about the evaluating segregation was protracted by Matlab program according to limiting ratios. At last, the segregation condition and its distribution in whole area according to four-dimensional chart of segregation effect were analyzed. Engineering application examples show that the evaluated result drew from this method agrees with practical situation of pavement. This method is convenient, non-destructive, which can provide reference of guidance for practical engineering.
