翔安大桥钢桥面铺装浇筑式沥青混合料施工技术

Construction technology of gussasphalt mixture in the steel deck pavement of Xiang’an Bridge

通过对翔安大桥进行钢桥面浇筑式沥青混合料的试验段铺装,阐述了浇筑式沥青混合料GA-10原材料选择、生产过程、运输过程、摊铺过程等环节,并现场测试了浇筑式沥青混合料GA-10的基本路用性能。翔安大桥钢桥面铺装试验段浇筑式沥青混合料的成功实施为主桥钢桥面铺装提供了技术支撑。

By paving the test section of steel deck gussasphalt mixture on Xiang’an Bridge,the raw material selection,production process,transportation process and paving process of gussasphalt mixture GA-10 were expounded,and the basic road performance of GA-10 was tested on site.The successful implementation of gussasphalt mixture in the steel deck pavement test section of Xiang’an Bridge provided technical support for the steel deck pavement of the main bridge.
