| 摘要： | The present study was undertaken to evaluate effects of Regular Sized Hydrated Lime (RHL) and Nano-Sized Hydrated Lime (NHL) on rutting, fatigue damage and aging resistance ability of asphalt mastic. VG-30 binder and different combinations of basalt - RHL, and basalt-NHL fillers were used for the preparation of asphalt mastic samples. Filler to binder (F/B) ratio was chosen as 0.8 (by mass ratio) for mastic sample preparation. Three different percentage of RHL and NHL were selected as 0％, 10％, and 20％ by weight of asphalt binder and amount of basalt filler was adjusted accordingly. The high temperature rutting resistance of asphalt mastic was evaluated using Super pave rutting factor. The fatigue damage resistance potential (number of cycles to fatigue damage) of asphalt mastic was estimated using Linear Amplitude Sweep (LAS) test. In addition, aging resistance behavior of asphalt mastic was addressed based on Super pave rutting parameter considering unaged and short term aged condition. The results indicate that NHL filler have better potential than RHL filler in improving the rutting resistance of asphalt mastic at high temperature. The NHL filler predominantly enhanced the fatigue life of asphalt mastic as compared to RHL filler. Aging resistivity results imply that contribution of NHL filler is significant over RHL filler in improving the oxidative aging resistance of asphalt mastic. Overall asphalt mastic with 20％NHL filler had better rutting, fatigue life, and aging resistance performance over mastic with other ％ of RHL or NHL fillers. |
