中文摘要：

通过对纤维沥青混合料的一系列性能试验，研究了纤维沥青混合料的高、低温性能和水稳定性．试验证明，掺纤维后沥青混合料高温稳定性增强，既吸附沥青又具有明显加筋作用的聚合物纤维效果较显著；纤维沥青混合料低温抗裂性提高，水稳定性改善，其中木质素纤维掺量合适的沥青混合料低温和水稳性效果明显．通过对混合料高温车辙试验结果的分析表明，采用“车辙变形的时间累积”指标和动稳定度指标综合使用可以更有效地评价混合料的车辙试验．

英文摘要：

This paper studies the fiber asphalt mixture capability through a series of the capability experiments, such as high and low temperature stability, water stability. Through the analysis of experiment results, the polymer fiber has strong ability to improve such stabilities. Cellulose fiber has strong ability to improve low - temperature and water stability when it be used suitably. It also puts forward a new index ＂time cumulation of wheel tracking deformation＂ to appraise wheel tracking test, and this appraiseal method is better than the index of dynamic stability.
