Background

The cement concrete pavement is a pavement which takes cement concrete as a main material and is used as a surface layer, and is called a concrete pavement for short. Also known as rigid pavement, commonly known as white pavement, which is a high-grade pavement. The cement concrete pavement is composed of various pavements such as plain concrete, reinforced concrete, continuous reinforced concrete, prestressed concrete and the like.

In the construction of cement concrete road surface, in order to ensure the skid resistance of the road surface, the grooving process is necessary, and the friction coefficient of the road surface is increased to ensure the safety of the vehicle running. Currently, common technologies for improving the skid resistance of a pavement include: plastic galling, grooving and notching. The pavement is textured, and the different textures cause the frictional forces of the pavement to be very different. When the road surface is dry, the texture can increase the friction between the vehicle and the road surface, and further ensure the safety of the vehicle in running.

Therefore, the person skilled in the art provides a construction method of a grooving grouting pavement with anti-skid and anti-frost cracking functions to solve the problems in the background art.
