The objective of this research was to select the most effective Warm Mix Asphalt (WMA) additives for WMA practice based on a series of laboratory testing programs such as density, Marshall stability, freeze-thaw splitting strength, dynamic stability, and bending beam strain. The experimental design of WMA mixtures included the use of three commonly-used WMA additives (Sasobit, Rediset and Evotherm), two types of aggregate (Basalt and limestone), and two types of asphalt (unmodified and SBS modified). Results showed that: (1) Most of WMA with Sasobit had the higher mechanical strength, whereas all WMA with Evotherm had the lowest. (2)When basalt Aggregate was used, Sasobit additive was the more effective on IDT and TSR. For all WMA, Evotherm additive was the less effective on IDT. (3) Sasobit additive had better effectiveness on resistance to rutting among all WMA. (4) When basalt aggregate was used, Rediset additive was more effective on bending failure strain. When limestone aggregate was used, Sasobit and Evotherm additive was more effective. |
