As a construction technology to improve the friction of the road surface and the depth of the structure,the milling process can quickly mill irregular longitudinal textures on the road surface without significantly improving the road noise and does not affect the driving comfort. At the same time, the bonding ability of the subsequent process paving materials or spray materials that may be produced is improved. Based on this, this article introduces the application occasions and performance of the milling process, the LX1850 pavement milling car and its specific application in the concrete pavement construction of Wushaoling No. 1 Tunnel. Research shows that its application greatly increases the anti-skid value of the original road surface. The pavement texture is uniform and does not harm the original pavement structure, which has a good social effect.
