Road surface structure of rolled press polymer modified cement concrete and its constructure method

Abstract

The invention relates to a grinding polymer modification cement concrete pavement structure and its construction method which refers to pavement project and its construction method, as well as concrete material and its construction method. The invention utilizes slurry mixed by the polymer and cement as the binding agent to felt the macadam and sand, it is formed to grinding polymer concrete pavement structure by grinding technology. Granular material of the grinding concrete is felted firmly to the slurry after adding the polymer. After the grinding concrete is hard set, it will become high intensity, great deformability, great water resistance, great ageing resistance, great corrosion resistance, great temperature stability. According to the different condition, different kind polymer material and use level are used to adjust the deformability of the grinding polymer modification cement concrete to make it present rigidity or flexibility. The grinding polymer modification cement concrete pavement structure adopts grinding technology; its advantages are the construction is expediently, the use less of the polymer and great economical efficiency and wide adaptation surface; high intensity, great deformability, great water resistance, and crack resistance.

Description

1. Technical field [0001] The invention relates to pavement engineering such as road engineering and a construction method thereof, as well as concrete materials and a construction method thereof. 2. Background technology [0002] 1. Background technology of cement concrete materials and construction methods [0003] 1.1 Cement concrete and current polymer modified cement concrete [0004] Cement concrete is a well-known building material. Although the development of concrete has only a history of more than 100 years, it has become the most widely used and used building material in the world, and it can be seen almost everywhere. Cement concrete uses cement paste of inorganic materials as the adhesive material to bond gravel and sand. Plastic cement concrete has a certain fluidity. In order to ensure the compactness of the solidified concrete, the vibrating process is generally used when pouring plastic concrete. After the cement slurry solidifies, it forms concrete as har...

AI Technical Summary

Problems solved by technology

[0007] The current polymer-modified cement concrete materials have the following main problems in use: when the above-mentioned first process is adopted, since the shrinkage of polymer-modified cement concrete is generally greater than that of ordinary cement concrete, even the polymer with the best shrinkage performance The shrinkage of modified cement concrete is only the same as that of ordinary concrete. Therefore, shrinkage compensation joints must be set when paving polymer modified cement concrete, and continuous laying is not possible.

Asphalt pavement has the advantages of smooth surface, no joints, comfortable driving, wear resistance, small vibration, low noise, and easy maintenance and repair. The pavement strength is not high, prone to rutting, loose spalling, reflection cracks and other damage
