摘　　要：湿热区的气候特点是高温、潮湿、多雨,在此种气候条件下钢桥面铺装的难点在于需解决桥面铺装高温稳定性和整个桥面铺装体系的防水性,以及施工工期短的问题,通过对湿热区高速公路跨线桥钢桥面铺装工程施工技术及实践的系统总结,形成一套完整的适宜于湿热区高速公路跨线钢桥浇筑式沥青混凝土的施工技术。The climate characteristics of humid and hot areas are high temperature,humidity,and heavy rain.The difficulty of steel bridge deck paving under such climate conditions lies in solving the problems of high temperature stability of bridge deck paving,waterproofing of the entire bridge deck paving system,and short construction period.Through a systematic summary of the construction technology and practice of steel bridge deck paving engineering for highway cross line bridges in humid and hot areas,a complete set of asphalt concrete construction technology suitable for highway cross line steel bridges in humid and hot areas has been formed.
