聚酯纤维沥青混合料在江苏省已得到较大规模的应用。文章通过掺加纤维和未掺加纤维的沥青混合料的水稳定性、高温稳定性、抗低温开裂等对比试验分析,研究了聚酯纤维沥青混合料的路用性能。对聚酯纤维沥青混合料作了简单经济分析。结合江苏省聚酯纤维沥青混合料的应用情况,提出了施工中的技术要点。研究表明,聚酯纤维沥青混合料具有良好的路用性能。聚酯纤维沥青混合料可作为江苏省解决沥青路面车辙问题和延长沥青路面使用寿命的技术选项。
Polyester fiber asphalt mixture in Jiangsu Province has been large-scale applications. In this paper, the pavement performance of polyester fiber asphalt mixture was studied by comparing the water stability, high temperature stability and low temperature cracking resistance of the asphalt mixture with and without fiber. Polyester fiber asphalt mixture made a simple economic analysis. Combined with the application of polyester fiber asphalt mixture in Jiangsu Province, the technical points of construction are put forward. Research shows that polyester fiber asphalt mixture has good road performance. Polyester fiber asphalt mixture can be used as Jiangsu Province to solve the problem of asphalt pavement rutting and prolong the service life of asphalt pavement technology options.
