1. Introduction to Fine Surface Emulsified Asphalt Products
Fine surface emulsified asphalt is a material modified by adding special additives to emulsified asphalt, which has better stability and construction performance. Compared with ordinary emulsified asphalt, refined emulsified asphalt has the following characteristics:
(1) Better stability: By modifying emulsified asphalt with additives, its dispersibility and stability are improved, thereby enhancing the quality and stability of the emulsion and improving the construction quality.
(2) Better construction performance: Fine surface emulsified asphalt has better fluidity and operability, which can be coated or laid in a shorter time, improving construction efficiency.
(3) Better water resistance: Fine emulsified asphalt can maintain the smoothness and color stability of the coating for a longer period of time, with better water resistance.
2. Preparation method of emulsified asphalt at the surface
The preparation of refined emulsified asphalt is mainly achieved by adding specific additives to the emulsified asphalt. Different types and amounts of additives can affect the performance of emulsified asphalt at the surface. In the preparation process, adopting reasonable technical means and process flow, such as high-speed mixing, adding temperature, etc., can improve the stability and construction performance of emulsified asphalt at the surface.
3. Application scenarios of emulsified asphalt on the surface
Fine emulsified asphalt is widely used in the repair and reinforcement of urban roads, highways, and other road surfaces. Its good stability and construction performance can effectively improve the quality and construction efficiency of the pavement coating layer, reduce the waste and loss of coatings, and improve the overall performance and service life of the pavement.
