In the long-term use of expressway asphalt pavement, due to repeated actions of vehicles and the impact of climate and environment, various damage phenomena are bound to occur. Due to the difference of environment, location, weather conditions, own quality and use conditions, Diseases are not the same situation, the common asphalt pavement disease vertical cracks, horizontal cracks, pit, rut, subsidence, pan oil and so on. The emergence of these diseases seriously affect the speed and safety, shorten the service life of asphalt pavement. Combining with the early diseases of asphalt pavement caused by the completion of the completion of the HeLong Expressway in Guangdong Province, the cause of asphaltic pavement diseases and the prevention measures are discussed.
