Performance Evaluation of Asphalt Mixtures Modified with Lignin Powder and Crumb Rubber

Abstract

AbstractThe use of biological additives in bitumen presents a promising path toward sustainable development, driven by economic and environmental benefits. These additives can reduce reliance on oil-derived bitumen, a finite and unsustainable resource. ...Practical ApplicationsThis research explored a sustainable approach to pavement construction by utilizing waste materials. We investigated the use of lignin, a natural byproduct from the paper industry, as an additive to asphalt mixtures. Our study ...
