摘要
通过室内试验,比较了三种桥面防水黏结体系(AMP-100、热熔SBS改性沥青撒碎石和AMP-100上铺热熔SBS改性沥青撒碎石)在不同温度环境中的剪切性能和黏结性能。试验结果表明,新型桥面防水黏结材料AMP-100上铺SBS改性沥青撒碎石的防水黏结体系性能最优,且受温度影响较小。针对江西省九景高速公路鄱阳湖大桥的气候特点及使用条件,将上述防水黏结体系应用于桥面铺装中,取得了较好的效果,对混凝土桥面铺装防水黏结体系的发展提供一定参考。
Through the experimental study,the shear and bond performance of 3 type waterproofing cementing system under different temperature wrer compared.Waterproofing cementing material AMP-100 covered by SBS modified asphalt with crushed stone behaved the best performance.In view of the climate characteristic and service conditions of Poyang Lake bridge in Jiangxi Province,this waterproof and cohesive system was used and had good Practical result.
