摘　　要：为评价沥青路面表面离析程度,控制沥青路面施工均匀性,采用手推式激光纹理仪(TM2)检测路面表面平均构造深度,提出采用平均构造深度比评价沥青路面表面离析。结果表明:TM2检测结果重现性较好,测试效率高、测试结果稳定。与传统评价方法相比,平均构造深度比可有效评价沥青路面表面离析程度。距边1 m位置检测路段存在20%的轻度离析,第一车道中间位置存在5%的轻度离析,摊铺机拼缝位置有15%的轻度离析。应加强护栏边部及摊铺机接缝位置碾压,并尽量减少摊铺机收斗次数,从而减少表面离析,提高沥青路面施工均匀性。In order to evaluate the degree of surface segregation of asphalt pavement and control the uniformity of asphalt pavement construction,a manually pushed laser texture analyzer(TM2)was used to detect the average structural depth of the pavement surface.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.There is a mild segregation of 20%in the road section detected at a distance of 1m from the edge.There is 5%mild segregation in the middle of the first lane,and 15%mild segregation at the joint position of the paver.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.
