摘　　要：桥面铺装是大跨径桥梁建设中的一个技术难点,其使用条件和使用要求都远高于道路路面。结合实体工程,通过大量室内试验,选定实体工程桥面铺装浇注式沥青混凝土层原材料,提出浇注式沥青混凝土的目标级配,确定浇注式混合料的最佳油石比,阐述了浇注式沥青混凝土的施工工艺。Deck Paving is a technical problem in the construction of long span bridges.The conditions and requirements of the application of surfacing are far more stringent than these of ordinary road pavements. Combined with a Bridge,by a lot of indoor experiments,pavement and with a lot of indoor experiments,raw materials of gussasphalt asphalt concrete are selected,and its mixtures proportioning design are put forward.At the same,its optimal asphalt content of are determined.Construction techniques of gussasphalt concrete are elaborated in details.
