在泥结碎石路面上加铺级配磨耗层,可以大大减低路面面层的粗糙,消灭坑洞、车辙、露骨和松散等现象。但路面铺筑磨耗层后,在车辆荷重压力产生的切向分力及因快速行车所形成的强力气流作用下,仍然会出现波浪、坑槽、松散等现象。也由于施工条件的限制,混合料中的粘结料不能完全匀布,使磨耗层的表面仍有许多空隙,便利了自然因素(温度、湿度、水分等)的侵蚀,影响了磨耗层的使用质量。采用“滚浆法”铺筑
The graded wear layer on the clay-bonded gravel pavement can greatly reduce the roughness of pavement surface, eliminate potholes, rutting, exposed and loose phenomena. However, after the pavement is worn by the pavement, the tangential force generated by the load of the vehicle and the strong airflow formed by the rapid driving may still cause waves, pits and looseness. Due to the restriction of the construction conditions, the binder in the mixture can not be completely uniformly distributed so that there are still many gaps on the surface of the wear layer, which facilitates the erosion of natural factors (temperature, humidity, moisture, etc.) and affects the usage of the wear layer quality. Adopting the “roller method” paving
