An Eco-Sustainable Stabilization of Clayey Road Subgrades by Lignin Treatment: An Overview and a Comparative Experimental Investigation
Subgrade conditions significantly affect functionality of the road pavement during its service life.Among the different stabilization techniques for upgrading poorly performing in-situ soil subgrades, an economically attractive example involves the use of waste materials, such as lignin.A deep bibliographic analysis of previous studies is carried o
