对特立尼达湖沥青在高等级公路沥青路面中的应用技术进行了研究,包括TLA改性沥青的技术性能研究、TLA改性沥青混合料的配合比设计、路用性能研究和施工质量控制技术研究,并且与SBS改性沥青的应用技术进行了对比研究。结果表明:TLA能明显提高沥青混合料的高温稳定性、水稳定性、抗渗性和耐疲劳特性,且其施工工艺与普通沥青混合料基本一致,价格比SBS改性沥青混合料更低,具有明显的经济效益和社会效益。
The application technology of Trinidad Lake asphalt in high-grade highway asphalt pavement is studied, including the technical performance of TLA modified asphalt, the mix design of TLA modified asphalt mixture, road performance study and construction quality control Technical research, and compared with the application of SBS modified asphalt technology. The results show that TLA can obviously improve the high temperature stability, water stability, impermeability and fatigue resistance of asphalt mixture. The construction technology of TLA is basically the same as ordinary asphalt mixture, the price is lower than that of SBS modified asphalt mixture, Has obvious economic and social benefits.
