Hydrated lime, as additive agent, was applied into asphalt mix to improve water stability. In this paper, asphalt retention ratio (According Schellenberg Leaking Test) and volume properties of asphalt mix containing hydrated lime, cement and conventional limestone mineral powder were comparatively investigated. The effect of hydrated lime on mastic asphalt was estimated using Dynamic Sheer Rheometer (DSR). The test results indicated that the asphalt retention ratio containing hydrated lime is superior to those of cement and mineral powder. At the same temperature, the viscosity and G*/sinδ of mastic asphalt containing hydrated lime increased apparently. To integrate the volume characteristics, asphalt retention ratio and mastic asphalt, the anti-stripping procedure of aggregate pre-damping using hydrated lime has been recommended.
