Abstract
Cracks are one of the common diseases of asphalt pavement in our country. “Cracks must be filled” is the basic requirement for preventive maintenance of asphalt pavement. There are two main methods for crack treatment. One is crack filling. Crack filling is an internationally commonly used method for crack treatment. The second is the crack seal band. This method is not widely used in foreign countries, but it has been widely used in China. This method is used in half of the crack treatment projects. The practice has proved that this method can improve construction efficiency and reduce the occurrence of secondary diseases compared with crack sealing. This chapter mainly introduces the materials, construction equipment, construction steps, operating conditions, indoor test methods, and quality inspection and acceptance of these two technologies.
