In many cases milled asphalt can be reused without additional crushing. It is common to resurface worn out asphalt by milling the top layer, so the new asphalt can be laid on an even surface. Many asphalt plants have the appropriate equipment to reuse reclaimed asphalt (RAP). The asphalt industry is one of the forerunners of recycling and reuse. Liquid Road is a polymer-modified, fiber reinforced asphalt emulsion surface treatment fortified with specifically graded aggregate for slip-resistance and durability. Recommended uses for Liquid Road: • Parking lots and other pavement surfaces • Low traffic roads and streets

Preventive Maintenance for Commercial Asphalt Pavement The fundamental benefit for the application of a surface treatment is to extend the life expectancy and performance of the pavement. It's important to understand the different types of surface treatments, and that it's not the function of a surface treatment to provide any structural improvement. Surface treatment | Asphalt emulsions | Entreprises Bourget Commonly known as economical paving, surface treatment is a road-surfacing method that uses crushed aggregates and asphalt emulsions.
