Evaluation Method for Surface Structure Segregation of Asphalt Pavement

In order to evaluate the degree of surface segregation on asphalt pavement, a manually pushed laser texture analyzer (TM2) was used to detect the average structural depth of the pavement surface, and it was proposed to use the average structural depth ratio to evaluate the surface segregation of asphalt pavement. The results indicate that the manual push laser texture analyzer (TM2) has good reproducibility, high testing efficiency, and stable testing results. Compared with traditional evaluation methods, the average construction depth ratio can effectively evaluate the degree of segregation on the surface of asphalt pavement. It is necessary to strengthen the rolling of the edges of the guardrail and the joints of the paver, and minimize the number of times the paver collects the bucket, in order to reduce surface segregation and improve the uniformity of asphalt pavement construction
