| Abstract: | Taking SMA-10 as an exemple water stability test,rutting test,dynamic and static creep tests,constant height repeating shear test(RSCH) and four-points bending fatigue test to study the influence of lignin fiber,mineral fiber and PAN fiber to asphalt mortar and its mixtures.were carried out by means of DSR,BBR The results showed that adding fiber in asphalt could significantly improve the high temperature properties of asphalt mortar and these mixtures while these low temperature crack resistance decreased.The freeze stability and the high temperature performance of mineral fiber asphalt mixture were better;the fatigue performance of PAN fiber asphalt mixture is excellent.The test results of rutting test,dynamic creep test and RSCH had good correlation and these results could preferably reflect the influence of various fibers to asphalt mixtures.The viscoelastic constants of dynamic creep test could predict the rutting of asphalt surface. |
