Asphalt emulsion
Description
- Asphalt emulsion is the product of properly mixing condensed asphalt with emulsifying agents and water in steady emulsion form.
- Condensed asphalt is the product of oil refining technology; includes polymer hydrocacbua compounds such as CnH2n+2, CnH2n, aromatic ring hydrocacbua (CnH2n-6) and some odd rings containing oxygen, nitrogen, and sulphur.
- Based on colloidal particle structures, asphalt emulsion can be classified into invert asphalt emulsion and asphalt emulsion upon. Based on the sticky- to- stone property, asphalt emulsion is classified into alkaline asphalt emulsion (well-sticked to stone originating from lime) and acidic asphalt emulsion (well-sticked to stone originating from silicon). Based on the popuplarity in use in Vietnam, this material just mentions acidic asphalt emulsion upon.
- In natural state, asphalt emulsion is liquid, dark brown and evenly.
- Depending on the splitting rate, asphalt emulsion can be classified into 3 types:
+Rapid-splitting asphalt emulsion
+Medium-splitting asphalt emulsion
+Slow-splitting asphalt emulsion
Application:
Asphalt emulsion is the material in the construction of roads, and transport works. Liquid asphalt emulsion is used to sprinkle the road surface or acts as the sticky layers between two sheets of asphalt concrete
PACKAGE & PRESERVATION
Commercial asphalt emulsion is preserved, transported in barrels with the capacity of 150 to 200 litre or by sprinkling-dedicated vehicle in normal temperature condition.
SAFETY – ENVIRONMENT
Asphalt emulsion is an oil-refining product, therefore, it can be harmful or badly affects the environment and human health if not preserved and used in accordance with proper technical procedure
