Asphalt road surface reinforcing material

Abstract

The road surface reinforcing asphalt material is one kind of post-added asphalt concrete modifier. It is prepared with PE, PP, POE, antioxidant 1010, stabilizer AT-168 and carbon black and through mixing. The road surface reinforcing asphalt material has wide material source and simple preparation process, and may be stirred and constructed with common asphalt mixer and matched with heavy traffic asphalt. Adding it in small amount of 0.3-0.7 % can raise the road use performance of mixed asphalt material, including strength, high temperature resistance, water resistance, etc. greatly.

Description

technical field [0001] The invention relates to an asphalt concrete modifier, in particular to a post-mixing modifier. Background technique [0002] Asphalt pavement has been widely used in my country's expressways, airport runways, urban roads and rural roads in recent years because of its driving comfort, low noise, and convenient maintenance. However, many highways and urban roads in our country have early failure phenomena such as rutting, cracking, and water damage shortly after they are completed and opened to traffic, which greatly shortens the service life of asphalt pavements and increases maintenance costs. This has attracted the general attention of the transportation department The main reason is that overloading is widespread, and ordinary asphalt pavement is difficult to meet the needs of overweight and overweight traffic. [0003] In order to prolong the service life of asphalt pavement, the highway construction department has take...

Problems solved by technology

However, many highways and urban roads in our country have early failure phenomena such as rutting, cracking, and water damage shortly after they are completed and opened to traffic, which greatly shortens the service life of asphalt pavements and increases maintenance costs. This has attracted the general attention of the transportation department The main reason is that overloading is widespread, and ordinary asphalt pavement is difficult to meet the needs of overweight and overweight traffic.

[0003] In order to prolong the service life of asphalt pavement, the highway construction department has taken many measures, such as using modified asphalt, adding fibers, increasing the thickness of asphalt pavement, and adopting expensive SMA asphalt pavement structure, etc. These measures have played a certain role, but the construction The cost has increased significantly
