Service life of traditional steel bridge deck pavement is significantly shortened due to the failure waterproof adhesion. To improve interlayer bonding performance and extend its service life, polyurethane proposed as a adhesion layer (WAL) for deck. This study aims synthesize WAL by free radical solution polymerization under different types dosages crosslinking agents well mixing ratio an acrylic co-blend. Tensile properties, water resistance, glass transition temperatures, thermal stability, adhesive strength binder are evaluated. The results demonstrate that yields desirable using hydroxyl molar 1/3 co-blend 65%. Specifically, tensile breaking elongation reach maximum values 6.466 MPa 268.4%, respectively. absorption rate less than 4%. Glass temperatures between -80 °C 60 °C, Polyurethane features remarkable high- low-temperature stability. Finally, plate reaches up 5.21 MPa. outcome this facilitates design application waterproofing layers decks.

Clarifying the action mechanism of steel slag and waste tire crumb rubber in asphalt mixtures is great significance realising solid resourcing improving road quality. This study focused on adhesion behaviour mixture from mixing to application explored SBS/crumb composite modified (SBS/CR CMA) multiple scales. The results show that SBS/CR CMA exhibit excellent properties during application, electrostatic force plays a leading role whole process. contribution 3CaO·SiO2 > 2CaO·SiO2. Among them, strong interaction between CR main improve property CMA. can slow down flow water molecules its surface, improves damage resistance slag-SBS /CR significantly. Selective occurs when mixed with different aggregates, object depends initial work aggregates.
