Abstract
An emulsion includes water; asphalt; an emulsifier in an amount of from about 0.5 to about 5 wt %, based on a total weight of the emulsion; a polyolefin having a weight average molecular weight (Mw) of from about 500 to about 30,000 Da; and a copolymer having at least two repeating units wherein a first repeating unit is a styrene residue, and a second repeating unit is a butadiene residue.
