Application of Waste Rubber Powder/SBS Double Compound Modified Asphalt in Xining South Beltway

Through the application of waste rubber powder/SBS double composite modified asphalt in Xining South Beltway, its superior road performance and construction feasibility have been verified. The road test results show that: The rutting stability of waste rubber powder/SBS double composite modified asphalt mixture reached 7800 times/mm, far exceeding the requirement of more than 3000 times/mm. The water stability and low-temperature bending performance also met the requirements of the index.
