摘　　要：以国内某著名大桥桥面铺装工程为研究背景,针对组合连续梁浇注式沥青混凝土GA10产生的气泡、鼓包现象,以外观表现、空隙率和弯曲应变比作为评价指标,在试验路上采取不同措施进行27种优化方案试验研究。研究结果表明:采用"环氧树脂+碎石+溶剂型粘结剂"作为防水粘结层能较好地解决组合连续梁浇注式沥青混凝土GA10的气泡、鼓包现象。研究成果可为其它类似桥面铺装工程提供较好的借鉴。With the deck pavement project of some famous bridge at home as the research background,in allusion to bubbles and bumps produced in casting asphalt concrete GA10, and with appearance performance,porosity and bending strain ratio as evaluation indices,this paper takes different measures on test road to perform experimental study of 27 optimized schemes. The results of study show that ＂epoxy resin ＋ gravel ＋ solvent based adhesive＂adopted as waterproof bonding layer can better deal with bubbles and bumps of casting asphalt concrete GA10. The results of study can provide a good reference for other similar deck pavement projects.
