Boulder County Road Maintenance uses two different products for Dust Control. After the road has been prepared for a dust control treatment, magnesium chloride is applied. Each year previously treated roads must be retreated with magnesium chloride and as the roads are retreated dust abatement improves.
Magnesium chloride is a great intermediate solution to reducing dust on low volume roads.
Lignosulfonates are left over after the pulping process removes the cellulosic material from the wood. Either one of these products may occasionally be used for base stabilization on some sections of roadway in Boulder County.
