沥青因其具有表面坚实、平整和无接缝等优点以及在后期养护上有着混泥土路面无可比拟的优势,在公路与城市道路中已广泛应用。然而,即使沥青路面设计是建立在层状弹性理论基础上的耐久性设计,沥青路面仍存在设计年限内发生的早期破损现象。 Asphalt has the advantages of solid surface, flatness and no seams, as well as unparalleled advantages of concrete pavement maintenance in the later period. It has been widely used in the road and urban roads. However, even if the asphalt pavement design is based on the durability design of the layered elastic theory, the asphalt pavement still has the early damage occurred within the design life.
