Polymer modified bitumen waterproofing membrane(for high-speed rail)

 

Product detail

Polymer odified bitumen waterproof material (for high-speed rail ) is specially used for High-speed passenger dedicated line’s bridge deck projects. It is made by saturating the modifier such as APP, SBS in bitumen, reinforced with polyester or fiberglass, finishing the two faces with fine sands, mineral slates(or grains)or polythene membrane etc. It is famous for anti-weathering.

 

Characteristic

1.Good performance in anti-erosion, anti-mildew, anti-weathering

2. Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.

3.Good impermeability

4.Adhesion realible.
