Polymer modified bitumen membrane

1. Product description:
    This product is a polymer modified bitumen membrane which takes    high polymer modified asphalt as the cover, polyester filament fiber felt  as the carcass and fine sand as cladding materials. 
2. The scope of application:
    It is used for railway bridges, highways, bridges and water-proof tunnel. In particular, apply to the waterproof layer on the extension of the low-temperature flexibility and more sophisticated engineering.
3. Features:
    This product is especially suitable for water-proof railway bridge, with excellent weathering performance and waterproof performance.
4. Technical indicators:
    This product is in line with the "passenger line Concrete bridge deck waterproofing temporary technical conditions (revised edition)" on the polymer modified bitumen membrane properties of the various technical indicators.
5. Usage and notes:
    First agent to deal with the grass-roots evenly, brushing the grass-roots level on the surface, do not open bottom and pile up as base agent become dry to pave the membrane. 
    paving start by the end of the bridge deck horizontal to the high-order; light the torch (gun), the baking sheet and the bottom layer of asphalt on the grass-roots level to deal with the agent, to bake evenly; the bottom sheet of asphalt melting layer, can be rolled forward, with the baking, paving and compaction, there must be squeezed out excess asphalt at overlap edge.
    May not wear spiked shoes involved in the operation, protective layer can be poured after paving 30 minutes.
The basic requirements of the grass-roots dry and the surface may not have open water.
6. Usage and notes:
    Stand on end or keep flat, should be 3 to a high degree of the membrane is limited, products to avoid the sun, rain, and not to undermine the quality of the membrane contact with the material and away from sources of heat.
