Evaluation of polyethylene (PE) modified asphalt prepared by different treatment methods: LDPE powder, LDPE + EVA blend, and maleic anhydride grafted PE

•Three PE modification routes are systematically compared under unified conditions.•Modifier treatment determines compatibility, dispersion, and storage stability.•PE-g-MAH improves high-temperature rutting resistance most.•LDPE + EVA achieves balanced high and low-temperature performance.•The suita...
