摘要：To study the effects of tourmaline type and content on the road performance of rubber powder modified asphalt mixture, different types of tourmaline rubber powder modified asphalt mixtures were prepared by adding tourmaline powder instead of equal weight mineral filler into the mixtures. Based on indoor simulation test, the high temperature stability, low temperature crack resistance and water stability of rubber powder modified asphalt mixture under different tourmaline type and content were systematically analyzed. The results show that with the increase of tourmaline powder content, the road performance of asphalt mixtures show an overall growth trend. The 60 °C of rutting test dynamic stability, the -10 °C of bending test flexural-tensile strain, immersion residual Marshall stability and freeze-thaw splitting tensile strength ratio of rubber powder modified asphalt mixtures with tourmaline powder increase by 12.5-19.6%, 7.5-12%, 1.8-4.7% and 1.7-4.3%, respectively.
