Embodiment Construction

[0020] Depend on figure 1 , figure 2 It can be seen from the comparison that the pavement texture structure obtained after diamond grinding not only has a macro texture, but also forms a jagged micro texture structure between the grooves, thus achieving good results in terms of noise reduction, anti-skid and flatness. .

[0021] Include the following steps:

[0022] 1. The contractor proposes a complete construction plan, including: types of grinding machines, types of level control instruments, flatness and skid resistance testing instruments and testing methods, sludge and wastewater collection equipment, grinding methods and scheduled construction progress, Types and specifications of seam repair and caulking materials.

[0023] 2. For new roads, the grinding construction can be organized after the joint construction of the surface layer is completed, after seven days of health preservation and the quality inspection is passed. At the same time, the timing of grinding ...

Abstract

The invention discloses a construction method for macroscopic and microscopic texture reconstruction of a cement concrete pavement. In the construction method, the cement concrete pavement is grinded by diamond blades with close intervals, a thin layer of 4-6 mm on the cement concrete pavement is grinded, the surface of the grinded cement concrete pavement is provided with grooves with longitudinal textures, and the grooves are arranged in a structure of a lamp wick shape. In the cement concrete pavement prepared by adopting the construction method for the macroscopic and microscopic texture reconstruction of the cement concrete pavement, the surface of the grinded cement concrete pavement is provided with the grooves with longitudinal textures, and the grooves are arranged in the structure of the lamp wick shape. After construction, the longitudinal texture with the lamp wick shape is formed on the pavement, and a zigzag configuration is also formed among the grooves while increasing the macroscopic configuration of the pavement. Through the formed longitudinal texture, the skid resistance performance of the pavement is enhanced, and the contact noise of tires and the pavement is reduced.

Description

Technical field: [0001] The invention relates to a cement concrete pavement and a construction method for reconstructing macroscopic and mesoscopic textures thereof, in particular to a construction method for anti-sliding and noise-reducing grinding of a cement concrete pavement. Background technique: [0002] Cement concrete pavement has the characteristics of high strength, good stability, long service life, and low maintenance cost. It is widely used in highway construction in my country, but its surface has functional defects such as poor anti-skid performance, poor flatness, and high driving noise. Limit its application in highway. [0003] Due to the limitations and constraints of our country's resources and energy, accelerating the development of cement concrete pavement and method progress is the objective demand of our country's expressway construction, and it is also an important strategic measure to promote the great development of our country's energy. And the ce...
