Asphalt pavement water damage in various forms. Generally can be summarized as three categories of loose type (road surface linen, loose, drop particles, pits), cracks (pumping pulp, net crack, pits) and deformation (rut groove). Above the early water damage phenomenon sometimes occurs alone, but most of the combination appears. For example, where the generation of the pulp is usually there will be cracks and deformation, and with the passage of time will soon appear loose and potholes. In addition, the water damage in accordance with the water on the road damage to the site, can be divided into road surface water damage to the road and into the pavement structure of the water damage to the road; in accordance with the formation process, can be divided into top-down surface layer Water damage and bottom-up water damage. Many of the initial pavement water damage occurred from top to bottom, and it is often confined to the surface layer where loose and pits occur when the surface water enters the road from the cracks and the larger fissures of the pores (China's recycled asphalt network) That is, the formation of pavement within the bottom of the water damage.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery

There are many factors that cause water damage to asphalt pavement, which can be divided into external factors and internal factors. External factors are mainly: water, load and construction methods; internal factors are: aggregate properties, asphalt properties, asphalt mixture porosity, asphalt mixture segregation and pavement structure drainage system. The occurrence of water damage is often the result of a combination of various factors. Asphalt and stone adhesion and insufficient mixture porosity is caused by asphalt pavement water damage the main reason. It is generally believed that the adhesion-peeling theory is the main mechanism of water damage. Adhesion refers to the physical effect of an object that binds to another object. Adhesion - peeling theory is mainly reflected in the two processes, that is, the adhesion and the loss of adhesive force. Loss of adhesion refers to the water into the interface between asphalt and mineral material, the mineral water on the suction than the asphalt suction, resulting in asphalt peeling; adhesive force loss refers to the asphalt within the water to soften the asphalt, viscosity decreased , Thereby reducing the integrity and strength of the asphalt mixture. There are four theories for the adhesion between asphalt and aggregate: mechanics theory, chemical reaction theory, surface energy theory and molecular orientation theory.
