Emulsified Asphalt
Emulsified Asphalt
Components of Emulsified Asphalt
Gilyoung asphalt emulsion is made to be used at room temperature without heating the solid or semi-solid state asphalt (straight asphalt) asphalt emulsion (emulsified asphalt, asphalt emulsion) is.
It is dispersed in water to the particulate of the asphalt.
At this time, the water with asphalt is not mixed each other.
The addition of an emulsifier, then the asphalt particles evenly dispersed in the water grind in a high-speed mill .
Moreover, almost of the range of a diameter of 1 ~ 5㎛ in the particle size of the emulsified asphalt. It is made markedly the charge on the surface of the asphalt particles prevent the particles from sticking together each other.
Type of emulsion asphalt
Emulsion asphalt is divided into three type. One is the asphalt emulsion type, another is anionic and non-ionic.
Refers to the anion, the electric charge of the cations that surround the asphalt particles are classified on the basis of the basic electrical laws to this classification system. In the non-ionic emulsion asphalt particles are neutral.
How quickly coalesce to asphalt, In other words depending on how fast curing or hardening does the emulsion can be classified in more detail, and to simplify and standardize this classification employed, the term RS, MS, SS. these terms are only as a relative concept, 'Rapid coagulation (rapid-setting)', 'medium-speed condensation (medium setting)', which means 'slow condensation (slow-setting)'.
The viscosity of the emulsion and the underlying associated with hardness of the asphalt using the serial number of the emulsion may be divided into more detailed cation means that before the emulsion type the letter "C" is the positive ion.
If "C" is without, meant a non-ionic or anionic.

Products of Gilyoung SNC
RSC-3,4
When construction of asphalt concrete road paving, it is using the adhesive before the paving material, pacving material paving before using the adhesive,
the emulsified asphalt RSC-3 is using adhesive before the basic floor paving,
the emulsified asphalt RSC-4 is using adhesive before the basic floor paving on surface course.
Packing standard unit is based on 200 kg per drum.
MINICOAT
Generally, MINI-COAT is using materials of emergency maintenance of road. MINI-COAT is a small amount to paving pavement surface, improved product for applied with an adhesive to the maintenance point, products to use for easy as a small package of 5 liter. ,
Fundamentally, MINI-COAT is producted based on emulsified asphalt.It is based on the ease of handling and excellent adhesion. And suitable for the construction of an emergency road repair.
How to use
* MINICOAT is recommended that before use, the product mix with surfaces of oil film by the mixing tools.
* Constructed under the air cleaning and good drying condition with the prevent debris of foreign substance
* Use the 0.6 ~ 1L / m2, before the paving the road repair.
* Be well up to the dry, after construction MINICOAT is sufficient curing time.
* After curing of the MINICOAT coating to add this scarcity areas of using.
* You should be careful not become a dirty around the others structures during the spray of MINICOAT.
Handling Precautions
- Can not be mixed with other types of emulsified asphalt MINICOAT.
- Do not incorporated into the debris during storage
- As possible as MINICOAT have to be mixing before using.
- Please thermal insulation in winter.
- Should not exceed 70 ℃ at heating MINICOAT
MODI – COAT
Recently MODI-COAT usage is increasing. When road paving of modified asphalt concrete, a lot of use of the adhesive for the surface of the pavement.
This represents an even more effective in open graded asphalt concrete and it is used to repair cracks in the road.
CMB (Cold Mix Binder)
CMB is asphalt emulsion of used for room temperature.
This is excellent adhesion and coating performance mixed compared with other coating asphalt. This product is excellent workability.
It reduces the physical properties and workability of the product expressed by adjusting the cure time for the product. CMB is adjusted the product standards and production according to the paving location.
CMB is able to reduce the physical properties and workability of the product expressed by adjusting the cure time for the product, transport, construction time.
