Construction Technology of Waterproof and Cohesive Layer in AC-5 Asphaltic Sand Bridge Deck

Considering the poor bonding effect of traditional sealing water layer for the concrete bridge deck, which has a bad influence on the durability of bridge deck asphalt pavement,the AC-5 asphaltic sand was used to act as a bridge deck waterproofing adhesive layer,and the corresponding key construction technology was stud-ied.The project practice indicated that the design scheme and construction effect were both desirable.
