纤维沥青混凝土路用性能研究

Study on Road Using Performance of Fiber Asphalt Concrete

该文通过对沥青混合料掺加纤维的研究,系统分析了纤维沥青混合料的路用性能,包括马歇尔稳定度、水稳定性、高温稳定性、低温抗裂性及耐疲劳性能;探讨了纤维增强沥青混合料的强度形成机理,并与普通密级配沥青混凝土进行了对比、分析。结果表明,纤维沥青混合料具有较好的路用性能,可以改善沥青路面使用品质,延长使用寿命。

Through the study of the asphalt mixture admixed with fiber, the article systematically an- alyzes the road using performance of fiber asphalt mixture including Marshall stability, water stability, high temperature stability, low temperature crack resistance and fatigue resistance, discusses the strength forming mechanism of fiber enhanced asphalt mixtures, and contrasts and analyzes the com- mon dense graded asphalt concrete. The result indicates that the fiber asphalt mixture has the better road using performance able to improve the service quality of asphalt pavement and to prolong the service life.
