Analysis of the Performance Impact of Rubber Powder Asphalt Mixture
In order to explore the performance of rubber powder(WRP)asphalt mixture,this experiment will implement the relevant requirements in the"Test Procedures for Road Asphalt and Asphalt Mixture",respectively using 0%,5%,10%of the amount of rubber powder asphalt mixture,carry out performance experiments,test items are as follows:penetration test,softening point test,15 ℃ elongation test,135 ℃ Brinell viscosity test,storage stability test.The final results show that the Brinell viscosity and softening point of composite modified asphalt increase,and the penetration decreases.Compared with the matrix asphalt,the rubber powder asphalt mixture has more excellent high temperature performance and storage stability.It can be concluded that it has the value of popularization and use.
