山西省作为能源重化工基地,山陵重丘区较多,在荷载较大的新建高速公路表面层、中面层、长大陡坡路段及高速公路大中修加铺层中使用TLA改性沥青,可以提高沥青面层高温抗车辙性能,增强低温抗裂性能,减少水损坏,减轻重交通沥青路面的早期破坏,延长沥青路面使用寿命,具有良好的经济效益和社会效益。文章主要针对特立尼达湖沥青混合料的路用性能进行研究。
As an energy heavy chemical industry base in Shanxi Province, there are more mountainous areas with heavy hills, and the TLA modified asphalt is used in the surface layer, middle layer, steep slope section and Dazhongxiuping expressway with large load. The invention can improve the anti-rutting performance of the asphalt surface layer at high temperature, enhance the anti-cracking performance at low temperature, reduce the water damage, reduce the early damage of the heavy traffic asphalt pavement, prolong the service life of the asphalt pavement, and has good economic and social benefits. The article mainly studies the road performance of Trinidad Lake asphalt mixture.
