Description

Technical Field

[0001] The utility model relates to the technical field of emulsified asphalt pavement paving, in particular to a cold-mixed and cold-laid emulsified asphalt pavement paving device. Background Art

[0002] Emulsified asphalt is a liquid asphalt that is produced by the reaction of asphalt and emulsifier under certain process, which is oil-in-water or water-in-oil (depending on the type of emulsifier). Emulsified asphalt is mainly composed of asphalt, emulsifier, stabilizer and water. According to the different properties of asphalt, emulsified asphalt can be divided into ordinary emulsified asphalt and modified emulsified asphalt. Emulsified asphalt is a road asphalt usually used at high temperature. After mechanical stirring and chemical stabilization (emulsification), it is diffused into water and liquefied into a road construction material with very low viscosity and good fluidity at room temperature. It can be used at room temperature and can also be used with wet and cold stones.
