    Abstract: Asphalt emulsions, methods of forming asphalt emulsions, and composite pavement structures formed from the asphalt emulsions are provided herein. In an embodiment, an asphalt emulsion includes a base asphalt component, water, and an oxidized high density polyethylene. The base asphalt component is present in an amount of from about 15 to about 70 weight %, the water is present in an amount of at least about 25 weight %, and the oxidized high density polyethylene is present in an amount of from about 1 to about 20 weight %, where all amounts are based on the total weight of the asphalt emulsion. The oxidized high density polyethylene has an acid value of from about 5 to about 50 mgKOH/g. The asphalt emulsion is free of aggregate and other mineral materials.
