| Abstract: | Combined with practical application of the Mazhu Dasuiduan highway ATB-25 flexible base, the charac- teristis of ATB-25 flexible substrate are analyzed with high temperature stability, low temperature crack resistance and water stability. For ATB-25 asphalt stabilized gravel＇s coarse aggregate is more, fine aggregate ratio is small, fast heat dissipation, the temperature dropped fast and so wide anti-segregation stand-alone paving, ＂followed by high tempera- ture, high-frequency low-amplitude, slow pressure less water, a combination of fiber reinforced＂ plasticthe rolling technology is summed up. It＇s an effective solution to segregation and the passage of RCC and other issues. |
