Asphalt Materials, Emuliscoat and Bituminous Materials .
Microsurfacing and Slurry Seal are surface seal treatments consisting of an emulsion, fine graded aggregates, performance enhancing additives, and water. Microsurfacing requires the use of a polymer modified asphalt emulsion. This application is designed for quick traffic return with the capacity of handling high traffic volume roadways.
Water in Asphalt Emulsion will evaporate and let the asphalt continuously form up as a film covering the aggregate or road surface. The speed of such formation depends on the quality (grade), usage volume and type of chemical used in the production of the Asphalt Emulsion.

Applications for asphalt emulsions | Asphalt magazine
This surface treatment can be used for maintenance on an asphalt or concrete pavement. It can also be used as a surface course on new asphalt pavement construction. The treatment is a one-pass paving process using a special machine that sprays a polymer modified asphalt emulsion, then places the ultrathin hot mix with a special screed.

Surface Treatment is the application of an asphalt emulsion on either an existing asphalt road or a fresh, compacted granular surface immediately followed by the application of a cover aggregate. It provides an economical all- weather surface for light to higher volume traffic depending on the emulsion and quality of .
High-Float Asphalt Emulsions | McAsphalt
In the case of high-float emulsions, the chemical charge is negative. The chemical type and quantity of surface-active agent used in the manufacturing process governs the process in which the resulting asphalt emulsion can be used. High-float emulsions have a gel structure, which prevents the flow of binder from high spots to low spots.
