Emulsified Asphalt
The emulsified asphalt for road pavement is a dark brown solution manufactured by adding special emulsifiers and stabilizers to asphalt and dispersing it into fine particles (1-3 μm) in water. This asphalt is mainly used for road pavement, and the cati onic emulsified asphalt is most widely used due to its excellent storage and adhesion performance.
Type
- RS(C)-3 (Rapid Setting Cationic - 3 ) : Prime coat
- This is a bitumen material sprayed to enhance the adhesion between the asphalt base layer and the sub base layer, which is a mixture of gravel and sand, and to improve the moisture and waterproof properties of the sub base layer (Amount to be sprayed: 1.0 ~ 2.0 liters/㎡ based on the specifications by the Ministry of Land, Infrastructure and Transport).
- RS(C)-4 (Rapid Setting Cationic - 4 ) : Tack coat
- This is a bitumen material sprayed on the asphalt base layer to improve the adhesion and moisture-proof and waterproof properties between the asphalt base layer and the intermediate layer or the surface layer that are laid on the prime coat (Amount to be sprayed: 0.3 ~ 0.6 liter/m² based on the specifications by the Ministry of Land, Infrastructure and Transport).
- SS(C)-1 (Slow Setting Cationic-1) : Tack coat
- It is recommendable to use SS(C)-1 in a new pavement where 24 hours of curing time can be secured after tack coat (Amount to be sprayed: 0.3 liter ~ 0.6/㎡ based on the specifications by the Ministry of Land, Infrastructure and Transport)
Winter Products
A-ONE Emulsion produces emulsified asphalt for the winter season by adding additives to prevent the product from freezing at -5°C to 7°C, which can slightly depend on the storage container, storage period, and climate from around November to February of the following year.

Handling Precautions
- Avoid mixing different types of emulsified asphalt.
- When using the product contained in a drum stored for a long time, roll or shake the drum before use.
- When spraying is difficult due to the low temperature in the cold season, it is convenient to use it with a little heating (60℃ or less).
- When storing the product in the winter, wrap it with a sheet, etc. to keep it warm so that it does not freeze.
