Problems solved by technology

[0004] However, none of the above technical solutions solves the problem that the adhesive surface of the self-adhesive modified asphalt coil is easily polluted by materials such as dust and cement powder on the construction site during the construction process, resulting in low surface energy of the self-adhesive surface, loss of adhesion and loss of adhesion. The failure of bonding with the base layer may easily lead to waterproof problems such as water channeling in the later stage
