Ligspec Dust Control

About Our Products

Ligspec Road Binder is a lignosulfonate which is derived from lignin which is nature's glue for binding cellulose fibers to form the rigid structure of trees. Lignin makes up about 25 - 35% of a tree. The binding action of lignosulfonate is a well-known characteristic that has found great utility in a variety of applications. Ligspec Road Binder is naturally tacky and exhibits excellent adhesive action on solid particles. This is principally due to the attraction of the lignin molecule to the fine soil particles. In certain instances, the engineering properties of some road bed soils can actually be improved because of the wetting and dispersing characteristics of lignosulfonate. It is a fact the use of lignosulfonate over time develops stronger interior soils. Many end users have found that roads impassable during the winter months are now passable after the application of our product.



Applied to any compacted native road bed surface, a water-diluted solution of Ligspec Road Binder can result in several economic benefits such as reduced road repairs, lower road bed material costs and lower equipment use costs. Ligspec Road Binder also will eliminate dust clouds and improve traction.


Ligspec Road Binder is designed for ease of use and efficiency in the suppression of dust in numerous applications. Ligspec Road Binder is easily mixed with water with minimum agitation, and can be applied with nearly any type of spray system.

Environmental Safety

Ligspec Road Binder is biodegradable, nontoxic and non-hazardous. It may be applied
around environmentally sensitive areas such as aquifers, lakes, streams, recreational facilities and residential areas. In addition, Ligspec Road Binder is non-corrosive, having a corrosion rate of tap water.

Application of Dust Control


 The application of Ligspec Road Binder consists
of mixing the concentrated product with
water in water trucks or special applicator
spreader trucks and applying the mixture in
multiple applications until the specified application
rate of concentrate is achieved. The
specified application rates of concentrate are
shown in Table I for different soil types. These
specifications are variable depending upon duration
of use and traffic loading.
