Study of the Physical and Mechanical Properties of Lignin-Modified Bitumen

Abstract

AbstractLignin, a prominent by-product of the wood and paper industry, presents a promising alternative to bitumen or a modifier to enhance the performance of bituminous mixtures. As a natural biopolymer, lignin offers the dual benefits of improving the ...The graphical abstract depicts the preparation of lignin-modified bitumen using VG30 bitumen and two types of lignin (A and B). It illustrates the mixing process with 5%, 10%, and 20% lignin content, the incorporation of basalt as an aggregate, and the ...
