    Abstract: Disclosed herein are latex compositions and asphalt formulations comprising the latex compositions. In some embodiments, the latex compositions include a styrene-butadiene copolymer and polyphosphoric acid represented by the formula, Hn+2PnO3n+1, wherein n is an integer from 2 to 30. The latex composition can be used to prepare polymer-modified asphalt emulsions and hot mix asphalt compositions. The asphalt formulations can be prepared by contacting asphalt with a latex composition as described herein and a sulfur curing agent. Methods of coating a surface comprising applying an asphalt formulation as described herein to the surface are also disclosed.
