摘要
通过室内试验对以A级70号和90号基质沥青制备的橡胶沥青的性能进行分析研究,试验结果表明,橡胶粉对沥青材料具有较好的改性效果,橡胶粉的加入提高了基质沥青的高温稳定性、弹性恢复性能和粘度,并且橡胶沥青的软化点比基质沥青也有显著的提高,改善了沥青的路用性能。
The function of rubber asphalt made of grade A No. 70 and No. 90 base asphalt is studied based on laboratory experiments. The results show that the rubber powder has better modification effect on asphalt material. The rubber powder is added to improve high temperature stability,elastic recovery properties and viscosity of the base asphalt. Compared with the base asphalt, the rubber asphalt softening point has been raised significantly. And the road performance of asphalt is also improved.
