纤维对橡胶改性沥青混合料路用性能影响研究

Study on the effect of fiber on pavement performance of rubber modified asphalt mixture

应用马歇尔试验确定不同纤维-橡胶改性沥青混合料的最佳掺量和油石比,在此基础上,采用高温车辙试验、低温小梁弯曲试验、浸水马歇尔试验及冻融劈裂试验,系统研究不同纤维-橡胶改性沥青混合料的高温性能、低温性能和水稳定性能等路用性能。

Marshall test was used to determine the best dosage and oil - stone ratio of different fiber - rubber modified asphalt mixture. Then high -temperature, low - temperature and water stability property of fiber - rubber modified asphalt mixture were evaluated by using high- temperature rutting test, low -temperature beam bending test, Immersion Marshall Test, and freeze - thaw split test.
