Modified asphalt waterproof coating for road and bridge
Features
●Water-based products do not contain toxic and harmful volatile substances and do not pollute the environment.
●It has elasticity, good extensibility, and can withstand the structural deformation requirements under dynamic load.
●Good heat resistance, high temperature resistance up to 140C ~ 160C.
●High bond strength, good shear resistance, and can effectively transmit horizontal traffic load.
●Liquid cold construction, no seam in the waterproof layer.
Executive Standard
JC / T975- 2005
Construction requirements
●Base layer treatment: The base layer must be firm and firm, with a smooth, dry surface, free of sanding, scumming, and obvious water collapse. The corners of yin and yang are rounded. The defective base can be treated with BPE-203 epoxy resin base treatment agent. Thoroughly remove debris, dust and oil stains before applying the film.
●Construction of waterproof layer of coating film: brush, roller or spraying method can be used, and the coating should be applied in layers, preferably 3 to 4 times. The next pass should be cured in the previous pass and formed perpendicular to the direction of the previous pass. The general interval is 4h ~ 7h (depending on temperature). The thickness of the coating is 1.0mmn, and the total amount of coating (2.2 ~ 2.6) kg / m2.
Precautions
●Before the concrete of the bridge deck is finally cured, it is better to perform regular and uniform brushing treatment on the concrete surface.
●The construction of waterproof layer can only be carried out when the concrete strength of bridge deck reaches at least 70% of the design strength.
●Waterproofing of bridge deck expansion joints, anti-collision wall expansion joints, bridge deck drains, etc. shall be handled separately according to the bridge structure waterproof design.
●The construction temperature is preferably 5 ℃ ~ 35 ℃. When the temperature is less than 5 ℃, rainy days (including the expected rain within 6 hours after construction) are not allowed.
●The waterproof layer is not completely dry. Do not allow people to walk and drive vehicles to prevent sharp objects from piercing the waterproof layer.
Storage and transportation
●Products are packaged in clean, dry and closed plastic drums or iron drums lined with plastic bags. The volume is 25kg / drum, 50kg / drum, 200kg / drum.
●The products are non-flammable and explosive materials, and can be transported as general cargo. During transportation, it should be protected against freezing, rain, exposure, squeezing, and collision, and keep the packaging intact.
●The product should be ventilated, dry and protected from direct sunlight during storage. The storage temperature should not be lower than 0 ℃. The storage period is one year.
