超薄沥青混凝土(UTAC)是20世纪80年代起源于法国的一种新型路面材料,它凭借其在防水、抗滑、平整、减噪等使用功能上的良好表现,在国外已被广泛采用,并在我国进行了初步的应用。但因其厚度薄,粒径小,又要求有较好的抗滑性能和密实性能,似乎存在一些矛盾。本文根据近年来国内外的相关研究,围绕超薄沥青混凝土配合比设计和超薄沥青路面结构的力学响应及结构与材料取值优化展开研究。
Ultra-thin asphalt concrete (UTAC) is a new pavement material originated from France in the 1980s. Due to its excellent performance in waterproofing, anti-slip, smoothness and noise reduction, UTAC has been widely adopted in foreign countries. And carried out a preliminary application in our country. However, due to its thin thickness, small particle size, but also requires good skid resistance and compact performance, there seems to be some contradictions. Based on the relevant researches in recent years, this paper focuses on the design of ultra-thin asphalt mixture and the mechanical response of ultra-thin asphalt pavement structure and optimization of structure and material value.
