摘　　要：浇注式沥青混合料摊铺时流动性大,常用于钢桥面铺装的保护层。当桥面坡度大时,浇注式沥青混合料在重力作用下流淌,可能导致铺装厚度不均匀。现综述日本的相关研究,重点介绍评价方法、材料设计和施工过程控制,为我国浇注式沥青混合料在大坡度段的施工质量控制提供参考。The gussasphalt has high fluidity during paving and is commonly applied as the protective layer for steel bridge deck pavement.When the slope of the bridge deck is steep,the gussasphalt flows under the gravity,which lead to uneven thickness.In this paper,the relevant research in Japan is reviewed.The evaluation methods,material design and construction process control are introduced.This paper provide reference for the construction quality control of gussasphalt on steep slope sections in China.

关 键 词：浇注式沥青混合料 钢桥面 大坡度 流淌 钢纤维
