It is called Lignosulfonate (sometimes referred to as “Lig”) and it is a dust control soil stabilization treatment? It is a naturally occurring polymer found in wood that acts like glue. Lignosulfonates work by binding the road surface particles together. Water evaporates from the lignosulfonate as it dries, and the dust particles are trapped by the high-viscosity, naturally sticky material. In addition, over time some of the lignosulfonates become completely insoluble due to solar heating.
