Study on the influence factors on the design and road performance of high-performance waterproof adhesive material for concrete bridge decks

The quality of the waterproof adhesive layer significantly impacted the safety and service life of concrete bridge deck pavements. Therefore, this study focused on the preparation of the waterborne epoxy resin-polyurethane-emulsified asphalt (WEPEA) and investigated the factors influencing its road performance. The component proportions of WEPEA were determined based on tensile strength and elongation at break, while its physical and chemical properties were systematically studied. Indoor tests were conducted to investigate the impact of environmental factors and surface treatment processes on WEPEA's road performance. The research findings indicated that the optimal proportions for WEPEA were 30% waterborne epoxy resin (WER) and 8% waterborne polyurethane (WPU). WEPEA exhibited excellent bonding performance, low-temperature flexibility, adhesion, waterproof properties, and corrosion resistance. Surface contaminants, freeze-thaw cycles, and immersion in water reduced the road performance of WEPEA. Surface treatments such as surface brushing, surface grooving, and surface milling enhanced WEPEA's road performance, with surface grooving being the most effective method. According to value engineering theory, compared to other waterproof adhesive materials, WEPEA had better economic benefits as a waterproof adhesive material.
