混凝土桥沥青混合料类防水材料的试验研究

Experiment Research on Waterproof Material of Asphalt Mixture of Concrete Bridge

防水材料对于桥面铺装来说非常重要。通过理论分析,结合室内试验,对几种沥青混合料类防水材料进行试验研究,得出沥青砂胶、沥青砂、稀浆封层和碎石封层都适用于混凝土桥面防水的结论,并提出这几种防水材料在使用中应该注意的问题,可供同行参考。

Waterproof material is very important for bridge surfacing.Through theoretical analysis and indoor test,experiment study has been done on several kinds of asphalt mixture of waterproof material.The result shows that asphalt mastic,asphalt sand,slurry seal and chip seal are all fit for the concrete bridge deck waterproof,and several problems deserving attention in using of waterproof material are put forward.
