Research of Road Application Performances of Asphalt Mixtures with Active Mineral Powder

In this paper the effect of Active mineral powder (AMP) on the fundamental behavior of asphalt concrete especially in moisture damage was studied. Polycyclic Soaking Marshall test and freeze-thaw and splitting test were used to investigate the resistance of mixtures to moisture damage. Dynamic stability of mixture was evaluated by soaking rutting and the fatigue life of asphalts mixture with and without AMP was measured by universal test machine (UTM). After adding AMP, Retained Marshall Stability, Tensile Strength Ratio and dynamic stability value of asphalt concrete is higher than that of non-containing AMP asphalt concrete. The failure life of asphalt concrete increased as adding AMP. The results showed that the addition of AMP could improve the performance of failure life and resistance to moisture damage.
