Product Description
Emulsified asphalt is a liquid asphalt with oil in water or water in oil formed by mechanical shear of asphalt and emulsifier under a certain process. It is mainly composed of base asphalt, emulsifier, additives and water.
The asphalt is heated and melted. Under the action of the machine, the asphalt is dispersed in the aqueous solution containing emulsifier by tiny particle state, forming an oil in water, relatively stable emulsion.
Product Features
1. The construction process is simple. Mechanical spraying or manual brushing can be used for construction, with fast drying and short construction period;
2. The waterproof layer is cheap, and generally only needs to be painted twice to three times to achieve the waterproof effect;
3. Strong adhesion. Penetrant and tackifier are added to the formula to improve the permeability and bonding performance of the coating, which can bond the pavement and bridge deck as a whole;
4. It has wide temperature adaptability, does not flow at high temperature of 140 ºC ~ 180 ºC during asphalt concrete construction, and does not crack under dynamic load at low temperature of - 20 ºC ~ - 30 ºC.
Scope of Application
It is applicable to waterproof projects such as expressway bridges, urban overpasses, bridges and culverts, can prevent reinforcement corrosion caused by water seepage of concrete bridge deck, and improve the service life of beam body.
Construction Process
1) The barrel coating shall be stirred evenly before brushing;
2) Before large-area painting, paint the leakage twice with a small brush, strengthen the painting of waterproof paint for internal corners for three times, and then paint once in a large area;
3) After the first coat of paint is dry, the second coat of material can be applied;
4) After the surface of the second coating is dry, apply the third coating.
