Dust Control

HOW CALCIUM CHLORIDE SAVES ROADS AND MONEY

• Improved dust control: Calcium chloride retains moisture for prolonged periods. This unique property helps to hold down dust and stabilize unpaved road surfaces, creating smooth-riding roads that last.
  
• Reduced routine maintenance costs: Since calcium chloride treated roads need less maintenance than roads treated with other materials, you can save on labor, equipment and fuel costs. By maximizing compaction, calcium chloride also provides a longer lasting road.
  
• Reduced gravel replacement costs: Up to 80% of the cost of aggregate replacement can be saved when calcium chloride is properly applied.
  
• Reduced construction costs: Because calcium chloride speeds compaction, less rolling is required to achieve greater density-which translates into greater labor savings. When used with full depth reclamation, calcium chloride can help reduce road reconstruction costs by as much as 50%.

Calcium chloride is a cost-effective-and highly effective-agent for dust control.
Calcium chloride:

• Can be reworked when the road surface is moist.
  
• reduces grading costs by as much as 50%
  
• reduces replacement cost of gravel and other materials by up to 80%
  
• reduces labor costs
  
• poses minimal threat to the environment, because it resists leaching. In fact, calcium chloride is used in food processing, fertilizers and as a nutrient in some applications.

APPLYING CALCIUM CHLORIDE FOR DUST CONTROL

0. Blade and shape the surface to allow water to drain off properly.
0. Apply liquid calcium chloride using a tank truck with a rear-mounted distribution bar that spreads the liquid evenly over the road.
0. For proper road maintenance, apply a second time later in summer.

CALCIUM CHLORIDE LEAVES OTHER AGENTS IN THE DUST

• Watercan't resist evaporation like calcium chloride; that's why water can only lay dust instead of control it. Once the water evaporates, you will have to water the road again. And frequent road watering adds up to greater operating costs.
  
• Oil is messy, chokes roadside foliage, and causes a crusty, pot holed, crumbling road surface when it dries. Oil also costs at least three times as much as calcium chloride.
  
• Oil emulsions are less expensive than oil alone, but as the water evaporates, the problems of oil-messiness and a crumbling surface -remain.
  
• Lignosulfonate, a by-product of paper mills, is less expensive than calcium chloride, but it lasts a fraction of the time. Frequent reapplication is necessary due to wash-out caused by rain-which translates into extra costs and reapplication maintenance trips.
