Analysis of Causes of Asphalt Pavement Diseases

Analysis of Causes of Asphalt Pavement Diseases With the rapid development of road transport in China, the number of transport vehicles has increased rapidly and the road transportation load has been increasing. This poses higher requirements for disease prevention and repair of pavements on asphalt roads in China. Driving on the highway, the flatness can directly reflect the road construction quality, and the flatness not only directly affects the ride comfort, but also has a crucial influence on the safety. In the construction of highways, asphalt pavements are widely used due to their smooth surface, comfortable driving, wear-resisting and anti-sliding, low noise, short construction period, and easy maintenance. Because of the structure of asphalt pavement, the occurrence and prevention of its disease has also become an important task for the road management department.

As China's road transport load gradually increases, roads with large amounts of bituminous pavements in China are facing serious diseases and other issues. The repair of current roads, especially the repair of asphalt pavements and disease prevention, is of great significance to ensure current road transport capacity and efficiency. .

As a road-use binder, asphalt concrete has been widely used in countries all over the world, from rural roads to urban roads, from tertiary roads to highways, from road base to pavement, all of which are commonly used as road construction. Long-term use of a material, but due to the asphalt material itself, as well as the impact of the design and construction level, the asphalt pavement often appear cracking, flooding, loose, pits and other diseases. The occurrence of these diseases has seriously affected the speed of driving and driving safety, increased car wear and shortened the service life of asphalt pavement.
