Abstract

Abstract: The latest research results at home and abroad have comprehensively analyzed the self-healing and repairing technology of asphalt mixture, and introduced the self-healing mechanism of asphalt and self-healing behavior of asphalt. Active and passive healing methods are mainly discussed. Both methods can effectively enhance the healing properties of asphalt materials and achieve the purpose of repairing cracks and looseness of asphalt concrete pavement. The development of self-healing asphalt concrete technology at home and abroad is expounded, and the application significance and application prospect of the technology are analyzed. The conclusion is that the environmental and social benefits of self-healing asphalt concrete technology are outstanding, and the promotion is of great significance and good development prospects.
