Therefore, the water permeable pavement can reduce water immersion streets and relieve urban heat island effect. The adhesive is one of key materials for manufacturing resin type water permeable bricks or water permeable pavements paved on site, and most of the adhesives are epoxy resin, phenolic resin, polyurethane and the like at present. The polyurethane adhesive has excellent shear strength and impact resistance, excellent flexibility and rubber characteristics, can adapt to the adhesion of base materials with different thermal expansion coefficients, has strong adhesive force, excellent buffering and damping functions, has low-temperature and ultralow-temperature performances superior to those of other types of adhesives, and is suitable for various structural adhesion fields.
