纤维沥青混合料三种车辙试验研究

Study on three rutting tests of fiber asphalt mixture

对添加了不同类型和不同掺量的纤维沥青混合料采用了TRLL、CPN和AAPA车辙试验,进行了纤维沥青混合料的抗车辙性能研究,结果发现,无论采用何种车辙试验方法,纤维均可以有效改善沥青混合料的抗车辙性能,而且聚丙烯腈纤维和矿物纤维的改善效果接近,均好于木质素纤维的改善效果。

For asphalt mixture added to different kinds and different containing fibers, TRLL, CPN and AAPA were used to study the rutting resistance of fiber asphalt mixture. The result shows that whatever the method ,fibers can improve the rutting resistance of asphalt mixture. And the effect of polyacrylonitrile fiber and mineral fiber is better than that of cellulose fibers.
