摘　　要：随着近年来山区高速公路项目的不断修建,长大纵坡及高温稳定性问题越来越引起路面工程师的广泛重视。此外,抗滑耐磨、抗低温裂缝、抗水损坏及特殊桥隧铺装等路面设计的综合矛盾也越来越突出。借助于沪蓉西高速公路的项目平台,对特殊地形气候条件下路面设计若干关键技术问题进行了总结。With the continuous construction of expressway projects in mountain areas in recent years, the problems of large longitudinal slope and high temperature stability has drawn increasing attention from pavement structure engineers. Besides, integrated contradictions on pavement design, such as slide and abrasion resistance, crack resistance at low temperature, water damage resistance and special bridge and tunnel paving, have become more and more distinct. Taking the project of Hurong west expressway as a platform, brief conclusions were made in this paper, focusing on key technical questions in pavement design under special topoclimate conditions. This paper can be a reference for the type selection of pavement structure for highways of the same type.
