The present disclosure provides embodiments of an asphalt composition and methods of making that may include asphalt binder; a recycled polymer component; an epoxy-functionalized ethylene copolymer, the epoxy-functionalized ethylene copolymer having the formula E/X/Y/Z. E may be a copolymer unit —(CHCH)— derived from ethylene; X may be a copolymer unit —(CHCRR)—, where Ris hydrogen, methyl, or ethyl, and Ris carboalkoxy, acyloxy, or alkoxy of 1 to 10 carbon atoms, present in from 0 to about 40 weight % of the copolymer; Y may be a copolymer unit —(CHCRR)—, where Ris hydrogen or methyl and Ris carboglycidoxy or glycidoxy present in from 0 to about 25 weight % of the copolymer; Z may be a copolymer derived from comonomers including carbon monoxide, sulfur dioxide, acrylonitrile, or other monomers, present from 0 to about 10 weight % of the copolymer.
