Abstract
At present, the fibers improve the performance that asphalt mixture resistance to water damage is still lack systematical awareness. For the different asphalt types, different fiber types, different fiber content of the asphalt mixture, the Marshall residual stability test and freeze-thaw splitting test are carried out, residual stability MS0 and the split strength ratio TSR are choosed as the measure indicators, the results show that: the addition of fibers and the use of modified asphalt can improve asphalt road performance obviously, modified asphalt is the better choice of improving the performance for mixture resistance to low-temperature water damage, the fiber types sorting for improving effects, whch is asphalt mixture’s performance for resistance to water damage, are obtained, and the optimal content scope of different fiber types are obtained too, research achievement can provide scientific guidance and reference for design and construction of fiber asphalt mixture.
