Now, asphalt pavement has been widely used in highway modified asphalt construction because of its many benefits. Now we mainly use hot asphalt and emulsified asphalt in asphalt pavement construction. Hot asphalt needs to consume a lot of heat energy, especially a lot of sand and gravel to bake heat, the working conditions are poor, and the labor intensity is high. When applying emulsified asphalt, no heating is required, and the coating can be sprayed or mixed at the temperature covered by different structural coatings. In addition, emulsified asphalt can move independently at temperature and can be made from emulsified asphalt of different concentrations, filling into molds if necessary or the permeability is simple to achieve the required asphalt thickness, which is not available with hot asphalt. With the gradual improvement of the travel network and the requirements for the reconstruction of low-grade highways, the use of emulsified asphalt will increase; with the gradual increase of environmental protection knowledge and the gradual increase in power intensity, the proportion of emulsified asphalt in asphalt will continue to travel, and the application plan will continue to increase. Will expand too, and the mass will trek. Emulsified asphalt has the characteristics of non-toxic, odorless, non-flammable, monotonous and fast, and strong adhesion. It not only improves the quality of the journey, but also expands the application planning of asphalt, prolongs the construction period, reduces environmental pollution, improves construction conditions, and saves money. Power, saving material.

Emulsified asphalt is mainly composed of asphalt, emulsifier, stabilizer and water.

1. Asphalt is the main material of emulsified asphalt, modified asphalt and its quality directly depends on the emulsification performance of asphalt.

Emulsifier is the key material of emulsified asphalt, which selects the quality of emulsified asphalt.

3. The stabilizer can make the emulsified asphalt have excellent storage stability during the construction process.

It is generally required that the water quality should not be too hard or contain other impurities. These impurities have an impact on the PHS and calcium and magnesium plasma of the water.

According to the different materials and emulsifiers used, the functions and uses of emulsified asphalt are different, and they are widely used: general emulsified asphalt, SBS modified emulsified asphalt, SBR modified emulsified asphalt, emulsified asphalt with extremely slow cracking speed, high permeability emulsified asphalt and high Viscosity emulsified asphalt. In the process of construction and repair of asphalt pavement, suitable emulsified asphalt can be selected according to the conditions and properties of the pavement.If you have any other questions, please contact us for details or modified asphalt contact us directly.
