product details
product introduction
the emulsified high-viscosity modified asphalt is used as a base material, and is made of a plurality of polymer modifiers, and is applicable to various bridge deck waterproof projects.
product advantages
(1) normal temperature construction, strong permeability, good leveling, energy saving and environmental protection;
(2) rapid film formation, good waterproof effect, and excellent high and low temperature performance;
(3) the adhesive force of the coating film and bridge base layer should be ≥ 0.4mpa, and the shear strength between the asphalt and asphalt pavement should be ≥ 1.5mpa to avoid the cracking of the pavement.
