不粘轮乳化沥青粘层在高速公路养护工程中应用评价
Application Evaluation of Trackless Emulsified Asphalt Tack Coat in Expressway Maintenance Engineering

本文以抗剪强度和抗拉强度作为沥青路面层间粘结状态的评价指标，分析不同乳化沥青对沥青路面层间粘结状态的影响，通过在高速公路养护工程中实际应用，验证了高性能不粘轮乳化沥青的使用性能，并进行了社会和经济效益的分析。结果表明：高性能不粘轮乳化沥青的层间粘结效果明显优于SBS改性乳化沥青和普通乳化沥青；高性能不粘轮乳化沥青在起到不粘轮效果的同时，可提供很高的路面结构层间粘结力；高性能不粘轮乳化沥青在新铺路面上的粘结效果比铣刨路面好；高性能不粘轮乳化沥青具有很好的经济效益和社会效益，推广应用前景广阔。
Taking the shear strength and tensile strength as the evaluation index of the bond state between layers of asphalt pavement, the influence of different emulsified asphalt on the bond state between layers of asphalt pavement is analyzed. Through the practical application in the expressway maintenance project, the usability of high-performance trackless emulsified asphalt is verified, and the social and economic benefits are analyzed. The results show that the adhesion between layers of high performance trackless emulsified asphalt is significantly better than SBS modified emulsified asphalt and ordinary emulsified asphalt; high performance trackless emulsified asphalt can provide a high adhesion between layers of pavement structure while playing trackless effect; the adhesion effect of high performance trackless emulsified asphalt on new pavement is better than milled pavement; high performance trackless emulsified asphalt has good economic and social benefits, and has a broad prospect of application.
