Abstract
A novel asphalt-aggregate composition in which the aggregate particles and the asphalt are separated by a very thin film of a water insoluble organic polymer. The continuous thin film is formed by treating the aggregate with dilute aqueous emulsion of the polymer. A major amount of hot treated aggregate is thoroughly mixed with a minor amount of hot, free-flowing asphalt to produce a composition useful in road construction and repair, roof maintenance, landfill lining and like application where the integrity of the asphalt must be maintained.
