Product Description
RWB-801 High Polyester Modified Asphalt Waterproof System Especially for Concrete Railway Bridge and Culvert
The service life of the prestressed concrete bridge is easily shortened by the water erosion. In the last several decades, many developed countries have been specializing in researches to improve the durability and prevention capability of the concrete. The present research has revealed the most effective solution to this problem: To lay a impermeable waterproof layer on the upper surface of the concrete bridge.
Beijing Oriental Yuhong waterproof Technology Co., Ltd. is one of first enterprises which have comprehensively carried out the research of the waterproofing technology for the concrete bridge. Besides, it is also the first one to find that the damage of the bridge waterproof membrane is actually caused by the traffic moving enforce and the distensible parts separation is caused by the water fluctuation pressure, which make the waterproof membrane much easier to be damaged. Besides, if the materials is used improperly, the leakage part will soon expand even when only one part begin to leak.
Our research has revealed the key indicators of the waterproofing layer on the concrete bridge: The adhesive ability, penetration&damage-resistant ability, fatigue-resistant ability and anti-aging ability under high traffic moveing pressure. On the basis of extensive testing, we have also revealed that petroleum asphalt is the most suitable waterproofing material because of its good performance on adhesion, heat-mold ability, water-resistance, anti-aging ability and its easy-modified nature. Hereby, we develop the High Polyester Modified Asphalt Waterproof Membrane --RWB-801, which specializes in the concrete railway bridge and the culvert construction with its permanent and high reliable performance.
This system can succeed to completely adhere the accidented surface with the BPR-203 substrate treatment agent especially for railway bridge and culvert, in which contains several kinds of anti-stripping agent to resist the infiltration spalling caused by water soakage.
When heated by the live fire, the surface of the RWB-801 waterproof layer can be made into hot-melt and adhesive liquid membrane which ensure the seamless bond with the concrete substrate of the bridge.
After being laid on the cement concrete protective layer, the special design surface of the RWB-801 high polymer modified bitumen membrane will bring a kind ""modified asphalt-quartz sand-silicate "" bonding interface with good bonding strength and shear resistance ability. This structure can undertake and transit traffic moving pressure to ensure the reinforced concrete structure of bridge will get a well protect during the construction engineering and long-term operation.
