摘　　要：为提高桥面铺装层的抗裂性,同时减少坑槽等水损害病害的发生,本文开发了一种不饱和聚酯树脂(以下英文简称UP)改性沥青桥面铺装材料,并对其配比和性能进行研究。通过粘度、动态剪切流变(DSR)和拉伸试验确定最佳UP改性沥青材料配比,对改性沥青流变性能和拉伸性能进行测试,并对UP改性沥青桥面铺装材料进行路用性能对比评估。研究结果表明,UP改性沥青具有良好的高温流变性,明显优于SBS改性沥青,且UP改性沥青与环氧改性沥青相比,具有更好的柔韧性,且价格便宜,其成本仅为环氧沥青的57%。此外,经测试,UP改性沥青桥面铺装材料的抗拉性能、高温稳定性也明显优于SBS改性沥青混合料,且与环氧沥青混合料相比,具有更好的低温抗裂性与水稳定性。In order to enhance the crack resistance of bridge deck pavement and simultaneously mitigate water-induced diseases such as potholes,this study developed a m-phenylene unsaturated polyester resin(UP)modified asphalt mixtures for bridge deck pavement and investigated the formulation and performance.The optimal formulation of UP modified asphalt was determined through viscosity,dynamic shear rheology(DSR),and tensile tests.Subsequently,the rheological and tensile properties of the modified asphalt were examined.Finally,comparative evaluations were conducted on road performance of UP modified asphalt mixtures.The results show that UP modified asphalt exhibits excellent high-temperature rheological properties,and surpasses those of SBS-modified asphalt significantly.Moreover,UP modified asphalt demonstrates superior flexibility compared to epoxy modified asphalt and has a more cost-effectiveness with a price approximately 57%lower than that of epoxy asphalt.Additionally,the tensile properties and high temperature stability of UP modified asphalt mixtures are significantly better than those of SBS-modified asphalt mixtures.They have better resistance to cracking at low temperatures and water-induced damage,compared with epoxy asphalt mixtures.
