Asphalt compositions including recycled polymer and epoxy-functionalized ethylene copolymer

An asphalt composition comprising:

• asphalt binder in about 70 to about 99.5 weight %, based on the total weight of the asphalt composition;
• a recycled polymer component in about 0.25 to 20 weight %, based on the total weight of the asphalt composition, wherein the recycled polymer component comprises:
• from 51 wt. % to 99.99 wt. % of a linear low density polyethylene, based on the total weight of the recycled polymer component;
• a polyamide;
• and
• an ethylene vinyl alcohol;
• and
• an epoxy-functionalized ethylene copolymer in about 0.1 to 10 weight %, based on the total weight of the asphalt composition, the epoxy-functionalized ethylene copolymer having the formula E/X/Y/Z,
• wherein E is the copolymer unit —(CH2CH2)— derived from ethylene;
• X is the copolymer unit —(CH2CR1R2)—, where R1 is hydrogen, methyl, or ethyl, and R2 is carboalkoxy, acyloxy, or alkoxy of 1 to 10 carbon atoms, present in from 0 to about 40 weight % of the copolymer;
• Y is the copolymer unit —(CH2CR3R4)—, where R3 is hydrogen or methyl and R4 is carboglycidoxy or glycidoxy present in from 0.1 to about 25 weight % of the copolymer;
• Z is the copolymer unit derived from comonomers including carbon monoxide, sulfur dioxide, acrylonitrile, or other monomers, present from 0 to about 10 weight % of the copolymer.
