Abstract:Aiming at the reasonable selection of waterproof adhesive materials for bridge deck pavement, the road performance of four kinds of materials was tested, and then analyzed by the grey target theory combining with the economic performance. The results show that temperature and water are important factors which influence the bonding performance of waterproof adhesive layer, and the effect is much more significant when the coupling effect of the two factors. The setting of waterproof adhesive materials can significantly improve the fatigue life of pavement structure, and the combination structure of SBS modified asphalt is the best. The SBS modified asphalt and synchronous gravel waterproof adhesive materials are the best grey target option, and it is recommended as a concrete bridge deck pavement waterproof adhesive materials.
