GP-RBM Modified Asphalt Waterproof Membrane For Roads And Bridges

Special modified asphalt waterproofing membranes for roads and bridges are made of thermoplastic elastomer (SBS), atactic polypropylene or atactic polyolefin (APP) plastic - modified asphalt as the coating material, polyester felt as the base, and covered with fine sand or polyethylene film on both sides as the isolation material. These membranes are specially designed for roads and bridges, featuring high - temperature resistance and shear resistance.

Product Features

●The product has high tensile strength and large elongation,and has tensile dependence on asphalt concrete cracks
●Resistant to corrosion by saline and chemical media,resistantto aging
●Excellent adhesive properties and high-temperature shear resistance,able to withstand high-temperature rolling construction when paving hot asphalt concrete,can effectively transfer and withstand traffic loads.
●Coil can be applied by cold bonding or hot melt construction
