对天然的剑麻纤维在不同掺量下沥青混合料的各项技术指标及掺量对技术指标的影响进行了分析,得出了剑麻纤维最佳的掺量为0.2%。进一步通过高温车辙试验、水稳定试验、低温弯曲试验和渗水系数试验对基体沥青混合料和剑麻纤维混合料的路用性能进行了对比。结果表明,剑麻纤维在最佳掺量下可以明显提高沥青混合料的路用性能。

The technical indices of asphalt mixture with different amounts of natural sisal fiber and the effect of mixing amount of fiber on the indices were analyzed,and the optimum mixing amount was determined to be 0.2%.A further comparison on the road performance of asphalt mixture and the one mixing with sisal fiber was carried out by means of the high temperature rutting test,water stability test,bending test and seepage coefficient test.The result indicates that the performance of asphalt mixtur...
