Dust palliatives are the agents applied to various road surfaces to prevent dust clouds and their environmental impact. The most commonly used dust palliatives are lignin sulfonate and magnesium chloride.

Most dust palliatives are spread directly to the road surface. Preparation is minimal. Depending upon road usage and weather conditions, a maintenance plan with subsequent applications is recommended.


Lignins are the “glue” that provides the strength in trees. Lignins are used in dust control and surface stabilization.

  • Creates a denser, firmer road cap
  • Water-soluble
  • Eco-friendly and non-toxic
  • Non-corrosive
  • Easy to handle and apply
  • Cost-effective
  • Requires no special equipment or clothing
Magnesium Chloride

Magnesium Chloride is a naturally biodegradable salt compound comprised of magnesium and chlorine and is used for controlling dust on a variety of road types. Magnesium chloride is hygroscopic, thus having the ability to attract atmospheric moisture from the surrounding air and holding this moisture in the top 2 inches of your road surface resulting in a dust free environment.

  • Eco-friendly
  • Leaves no residue
  • Colorless and odorless
  • Hygroscopic (attracts moisture)
  • Can be used down to 5° F
