Modified bitumen membrane weatherability

The present invention discloses a modified bitumen membrane weatherability to as polyester felt or glass fiber mat reinforcement, reinforcement of the upper asphalt layer coating weatherability, reinforcement-melt coating the following modified bitumen layer, the surface coating layer weather resistance mineral particles modified bitumen layer, the surface coating film-melt polyethylene modified asphalt layer. Weatherability modified bitumen membrane of the present invention, long life, high water resistance and good aging resistance, low application temperature, high temperature aging reduces modified asphalt and environmental pollution, may be used for different regions, different environments industrial and civil construction roofing projects at the temperature.
