摘要
目前,废胶粉改性沥青生产主要有干法和湿法两种。废胶粉在沥青中主要发生胶粉微粒的膨胀和橡胶中交联网络的降解两种变化。沥青组分、废胶粉的表面形态及加工工艺是影响废胶粉改性沥青的主要因素。
The dry method and wet method are the main methods of producing crumb rubber modified asphalt at present.The crumb rubber mainly occurs two changes in asphalt which are the expansion of the rubber particles and the degradation of rubber cross linking network.The main factors affecting the crumb rubber modified asphalt are the components of asphalt,the surface morphology of crumb rubber and the processing technic.
