Problems solved by technology

[0002] Asphalt is often used to pave roads. In the high temperature season in summer, rutting is prone to occur under heavy loads. In the cold season of winter, temperature shrinkage cracks are prone to occur. This is mainly due to the low tensile strength under high temperature conditions and high brittleness under low temperature conditions. , poor flexibility
Long-span steel box girder structure bridges put forward higher requirements on the strength, deformation stability and fatigue durability of the pavement materials. Special requirements such as cohesiveness and impermeability, as an important part of the bridge traffic system, the quality of bridge deck pavement directly affects the safety, comfort, bridge durability and investment economic benefits of traffic. Therefore, ordinary asphalt can no longer be used. To meet the above requirements, modified asphalt must be used
