摘要
为改善橡胶沥青的路用性能,采用次氯酸钠对橡胶粉进行活化处理,研究了不同活化橡胶粉掺量下的橡胶沥青的路用性能,并与未经活化处理的橡胶沥青路用性能进行对比。结果表明:次氯酸钠活化橡胶粉能够进一步提高橡胶沥青的高温性能、低温性能、弹性恢复性能和施工和易性。
In order to improve the pavement performance of rubber asphalt,sodium hypochlorite is used to activate the rubber powder.The pavement performance of rubber asphalt under different mixing amounts of activated rubber powder is studied and compared with that without activating treatment.The results show that:the activated rubber powder of sodium hypochlorite can further improve the high temperature performance,low temperature performance,elastic recovery performance and workable performance of rubber asphalt.
