钢桥面铺装防水体系防腐性能的评价

根据自然环境与桥面使用功能对钢桥面铺装防水体系防腐性能的特殊要求,选用4种目前应用的典型钢桥面防水体系材料（含防腐层）,制定钢桥面铺装防水体系防腐性能的评价方法（盐雾、酸雾试验）及其评价指标,对4种材料的防腐效果进行试验评价,并分析其防腐性能差异的成因。试验结果表明：各类材料的防腐性能存在较大的差异,钢桥面防水材料（含防腐层）的优选不能忽视防腐性能的评价;采用盐雾、酸雾试验可以很好地评价钢桥面铺装防水体系的防腐性能。

Evaluation on anticorrosion property of waterproof system on steel deck pavement

According to the special requirements of natural environment and deck function to anti-corrosion performance of steel deck pavement waterproof system,four steel deck pavement waterproof system materials(including anticorrosion coating)which are typically used now were tested for evaluating their anticorrosion effect,the causes of their different anticorrosion performance were analyzed by salt spray and acid mist tests to get the evaluation indices.The results show that there are greater difference in anticorrosion performance of the four materials,and the anticorrosion performance evaluation for the optimization selection of steel deck pavement waterproof material(including anticorrosion coating) should not be ignored.The salt spray and acid mist tests can effectively evaluate the anticorrosion performance of the system.1 tab,13 figs,10 refs.
