聚脂纤维沥青混合料性能的试验研究

在沥青混合料中掺加聚脂纤维,通过室内试验对沥青混合料的高温稳定性、低温抗裂性、水稳定性等路用性能进行研究,对试验得出的各项路用性能指标进行有针对性的分析,得出加入聚脂纤维能有效改善沥青混合料的路用性能,但在使用上应根据具体工程的交通条件和气候条件,通过试验进行科学的选择.

Research on Test of Polyester Fiber Asphalt Mixture for Performance

For admixing the polyester fiber into asphalt mixture,the paper makes research on road usage performances such as the stability of asphalt mixture at high temp,the crack-resistance at low temp as well as the water stability etc by experiment in lab,analyzes targets of all kinds of road usage performances.Results of research show that admixing the polyester fiber into asphalt mixture is able to effectively improve road usage performance of the latter.However,the scientific selection of its using should be carried out according to traffic and limate conditions through experiment.
