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.
