| 摘 要： | 通过对橡胶沥青进行电镜分析,认为橡胶沥青形成机理可以解释为胶粉与基质沥青在高温条件下混合后同时发生物理和化学两种反应.胶粉颗粒发生物理溶胀反应,同时胶粉颗粒表面与基质沥青形成凝胶体,彼此相连形成似网状结构.对不同规格胶粉、不同胶粉掺量、不同反应时间和不同反应温度所生成的橡胶沥青进行对比试验,并对橡胶沥青混合料的性能以及...

| Abstract: | Based on the results of electron microscope observation,the formation mechanism of rubber asphalt can be explained as follows: Both chemical and physical reactions take place when crumbed rubber and base bitumen are mixed together at high temperature.Physical swelling of the crumbed rubber particles takes place during the process,at the same time a layer of gel forms on the surface of crumbed rubber particles and base bitumen,through which the particles connect with each other and a network structure is for... |
