Effect of Mineral Powder on Performance of Unaged and Aged Asphalt Mortar

Abstract:

In order to analyze the effect of mineral powder on the high-temperature rut resistance and fatigue cracking resistance performance of unaged,short-term and long-term aged asphalt mortar, Dynamic Shear Rheometer (DSR) was used to study different powder/bitumen ratio of asphalt mortar. The results indicate that increasing mineral powder content can improve high-temperature rut resistance performance of asphalt mortar, but decrease its fatigue cracking resistance performance. As the experiment temperature rises, high-temperature rut resistance performance of different asphalt mortar will decrease, on the contrary, rising fatigue cracking resistance performance.
