摘要
纤维沥青也是改性沥青的一种。通过车辙试验,以动稳定度为指标来评价沥青混合料的高温稳定性。研究表明,外掺纤维沥青混合料在最佳油石比下具有很好的高温稳定性,而素沥青混合料在最佳油石比下纤维的介入同样可以改善其高温性能。
Fiber bitumen also is a kind of modified bitumen. Through wheel rutting test, the value of dynamic stability is used to analyze the high temperature stability of asphalt mixtures. The study indicates that the fiber asphalt mixtures in the optimum asphalt-aggregate ratio have good high temperature stability. The high temperature stability of the pure asphalt mixtures in the optimum asphalt-aggregate ratio can also be improved with the adding of fibers.
