Introduction to the uses of emulsified asphalt First, its application in the highway industry. Emulsified asphalt is divided into many types, which are generally classified according to their uses. The asphalt emulsifiers used for emulsified asphalt of different uses are also different. In the highway industry, emulsified asphalt is generally used in: micro-surfacing and slurry seal, asphalt pavement cold regeneration, gravel seal, penetration layer, adhesive layer, cold repair material, cold grouting material, grouting material, etc. Their uses are different, and the emulsified asphalt used is also different. The difference in emulsified asphalt is generally reflected in the difference in asphalt emulsifier, pH and ionicity. For example: the emulsified asphalt used for penetration oil is high-penetration emulsified asphalt. The emulsifier used for high-penetration emulsified asphalt is generally a slow-cracking asphalt emulsifier (ZT-CZ2). The slow-cracking type is reflected in the slow demulsification time of the emulsified asphalt. The emulsified asphalt is still in the water-emulsion type when sprayed on the road surface, which is conducive to penetrating into the roadbed, thereby playing a waterproofing role. The emulsified asphalt for spreading tack coat is generally medium crack emulsified asphalt (ZT-CZ1/ZT-CZ2 asphalt emulsifier). The slurry seal and micro-surfacing use slow cracking and fast setting emulsified asphalt (ZT-CMK2/ZT-CMK3/ZT-CMK4/ZT-CMK5/ZT-CMK6), etc. The cold production of asphalt pavement also uses slow cracking asphalt emulsifier (ZT-CZ2).

The application of emulsified asphalt in high-speed rail is generally used in the production of CA mortar.
Emulsified asphalt is widely used in building roofs and cavern waterproofing, and anti-corrosion of metal material surfaces. The emulsified asphalt used is different according to the formula of each manufacturer. Our company produces anionic/cationic asphalt emulsifiers specifically for waterproofing and anti-corrosion.
At present, we are vigorously promoting the new building material waterproof coating: spray quick-setting waterproof coating, whose base material is also emulsified asphalt.
The use of emulsified asphalt in agriculture. Emulsified asphalt can be used as the main raw material of sand fixation agent, which is suitable for desert sand fixation, soil improvement, plant cultivation, etc. In addition, emulsified asphalt is also used as oil field drilling fluid, oil field water plugging agent, etc.
