Fyt-1 bridge deck Waterproof coating
1、 Product Introduction
Fyt-1 Bridge deck waterproofing coating The price is based on a large amount of composite polymer, with a small amount of Petroleum asphalt A new type of composite waterproof coating is made through fine preparation. The coating not only has good elasticity, plasticity, heat resistance and cohesiveness of high molecular polymer, but also has good compatibility with petroleum asphalt The product has good affinity. In order to adapt to the construction under the high temperature condition of asphalt concrete, it has become a waterproof construction coating for various bridges and viaducts.
2、 Main features
1. Cold construction: FYT-1 bridge deck waterproof coating product is a single component Waterborne paint It does not need to be heated during use, has no harmful volatile gas, is harmless to human body, has no pollution, and belongs to environmental protection products.
2. Simple construction, easy repair, low product viscosity, and can be sprayed or brushed; High construction speed and low labor intensity. When paving asphalt concrete, if the waterproof layer is damaged, just brush it again at the damaged place.
3. The material performance is good. After film formation, the elongation is large, the crack resistance is good, the high temperature does not flow, the low temperature does not embrittlement, and the temperature resistance is good.
4. The adhesive strength and shear strength of asphalt concrete pavement and cement concrete bridge deck are studied, and the service life of asphalt concrete is also calculated.
3、 Implementation of technical indicators: JC/T975-2005
S/N Item Index

4、 Scope of application
The price of fyt-1 bridge deck waterproof coating is applicable to the waterproofing of urban viaducts, overpasses, overpasses and highway bridges. It is also applicable to highway and municipal traffic engineering supporting facilities, such as box and box pipe joints, and external waterproofing of underground buildings.
5、 Precautions
1. Construction shall not be carried out in rainy days or when it rains within 6 hours after the construction is expected and there is ponding on the bridge deck. The temperature is less than 5 ℃, and construction is not allowed between 11:00 p.m. and 3:00 p.m. in high temperature season.
2. Before the waterproof layer is dry, it is not allowed to walk or drive vehicles. It is better to pave asphalt concrete after 48 hours of curing.
3. It is forbidden to spray adhesive oil on the sprayed waterproof layer.
4. During asphalt paving, the wheel of the load material shall be kept clean and wet, the vehicle shall run slowly, and it is strictly prohibited to brake suddenly or turn around locally within 5 meters around the bridge support.
5. If the waterproof layer is damaged, it shall be repaired in time.
