Description

technical field [0001] The application belongs to the field of asphalt waterproof materials, in particular to a styrene-butadiene rubber modified asphalt waterproof material. Background technique [0002] Many changes have taken place in modern highways and roads: the traffic flow and driving frequency have increased sharply, the axle load of freight vehicles has continued to increase, and one-way driving in separate lanes is generally implemented, which requires further improvement of the anti-flow performance of the road surface, that is, the ability to resist rutting at high temperatures; Flexibility and elasticity, that is, the ability to resist cracking at low temperatures; improve wear resistance and extend service life. Modern buildings generally use long-span prestressed roof panels, requiring roof waterproof materials to adapt to large displacements, more resistant to harsh high and low temperature climate conditions, better durability, self-adhesive, convenient con...
