摘　　要：浇注式沥青混合料具有不透水、整体性强、柔韧性好和抗老化性能优良的特点。近年来在大中型桥梁、特别是在钢桥桥面铺装中得到了较多的应用,引起了人们的关注。本文从铺装使用的交通条件、气候条件以及混合料的设计等方面出发,着重就浇注式沥青混合料配合比设计在贵州北盘江大桥桥面铺装中的应用进行介绍,为我国的相关研究提供有益的借鉴。Gussasphah mixture has a smooth, impervious, strong integrity, flexibility and good performance anti-aging characteristics. In recent years, gussasphah mixture has been widely used in the large and medium-sized bridges, especially in the steel bridge deck pavement, which attracted attention. From the use of bridge deck pavement traffic conditions, weather conditions, as well as the design factors of mixture, this paper focuses on introducing the gussasphalt mixture design in Guizhou Beipanjiang Bridge Deck, which can provide useful lessons for our similar research.
