Sustainable Cutback Bitumen from Transesterified Waste Cooking Oil: Development, Characterization, and Performance

Abstract

Abstract Sustainable and environmentally responsible alternatives to conventional diesel-based cutback bitumen are increasingly needed in pavement construction due to the environmental impacts of diesel, dependence on nonrenewable resources, and safety ... Practical Applications This research demonstrates a practical pathway for reducing diesel use in cutback bitumen by partially replacing it with fatty acid methyl esters (FAME) produced from waste cooking oil. The proposed diesel–FAME cutback systems can ...
