摘要：
The current research studied the characteristics of warm mixture asphalt (WMA) contain Polypropylene polymer (PP) and Nano- silica particles (NS). Two kinds of WMA were used: unmodified WMA and modified WMA contain 3% PP and NS (2-5) % by total weight of asphalt. The performance tests conducted to evaluate performance are: moisture resistance test, rutting resistance test, and fatigue resistance test. The obtained results refers that addition Nano- silica and Polypropylene improves performance of WMA. Also the results reveals that addition of Nano- silica and polypropylene as asphalt modifiers increase durability and improve performance of warm mixtures asphalt.
