众所周知,通过在沥青中加入聚合物如SBS、A PP等,可以在保持沥青本身优点的同时改善其粘弹行为。通过加入废塑料细粒子,同样可以改善沥青的低温塑性和弹性,而且高温时的这种分子联结也能得到有效保持。废塑料的活化既可以采用接枝共聚,也可以通过臭氧处理使其与沥青反应。活化 It is well known that by adding polymers such as SBS, A PP and so on to bitumen, its viscoelastic behavior can be improved while maintaining its own advantages. By adding fine particles of waste plastics, the low temperature plasticity and elasticity of the asphalt can also be improved, and the molecular linkage at high temperature can be effectively maintained. Activation of plastic waste can be either graft copolymerization, but also by ozone treatment to react with the asphalt. activation
