Dust Control

Dust Control

Products

  • W 1.32 calcium chloride (cacl2)
  • MG-30 calcium chloride/magnesium hydroxide

Applications

  • Calcium chloride is easily applied following the Kortech Calcium Chloride Application Protocol Benefits
  • Increases safety through increased visibility on rural roads.
  • Dust particles (fines) are not blown into adjacent homes creating health complications in the human respiratory system.
  • Dust particles (fines) are not blown onto adjacent environmental areas, such as bodies of water.
  • Calcium chloride has both; an easy application process and also a low cost, making calcium chloride the most widely used dust control agent on North American rural roads.
  • Calcium chloride has proven to reduce gravel loss by up to 40%. Reducing re-graveling costs help reduce the overall maintenance cost.
  • Treated road surfaces may be bladed, which will not result in substantial product loss.

Structural Stability

Calcium chloride provides a hardened road surface and a stronger base reducing maintenance costs and road surface problems.

Freeze Thaw Stability

Calcium chloride reduces frost heaving caused by the freeze thaw cycle. Deep penetration of calcium chloride can reduce spring and fall maintenance costs by reducing road surface and base maintenance work costs.

Environmental

  • Calcium Chloride is non-toxic and does not require any placarding during transportation. Tests conducted by the Department of Highways in Ontario show Calcium Chloride is non-toxic and does not require any placarding during transportation. Tests conducted by the Department of Highways in Ontario show Calcium chloride to be the least aggressive agent among dust palliatives.
  • Calcium chloride is not palatable to wildlife, keeping wildlife away from treated road surfaces.

Cost

  • The availability of naturally occurring Calcium Chloride Brines in Alberta has lowered the costs of calcium chloride brines Western Canada.
  • Utilization of Calcium Chloride lowers the road construction costs as the densities are attained more readily.
  • Maintenance costs are reduced dramatically on a season to season basis.

Quantity needed

Q:How much calcium chloride is needed to treat my roadway for dust control?
A:For dust control applications we recommend between 1.5 litres and 2.0 litres per square meter at a depth of 2 inches.

Area of Roadway (length x width) Width of Roadway (meters) 5m 7m 10m
Step 1:find the surface area of the roadway (length x width)
Length of Roadway (meters) - - - -
100 m (0.1 km) - 500 m2 700 m2 1000 m2
200 m (0.2 km) - 1000 m2 1400 m2 2000 m2
500 m (0.5 km) - 2500 m2 3500 m2 5000 m2
1000 m (1 km) - 5000 m2 7000 m2 10 000 m2
Product needed (area x application rate) Area of road surface (m2) 500 m2 2500 m2 10 000 m2
Step 2:calculate the product needed (area x application rate)
Application rate (litres per m2) - - - -
1.5 litres per m2 - 750 litres 3750 Litres 15 000 Litres
1.7 litres per m2 - 850 Litres 4250 Litres 17 000 Litres
1.5 litres per m2 - 750 litres 3750 Litres 15 000 Litres
1.7 litres per m2 - 850 Litres 4250 Litres 17 000 Litres
2.0 litres per m2 - 1000 Litres 5000 Litres 20 000 Litres

FAQ

Q:Will I need to add additional aggregate to my roadway surface?
A:Fresh aggregate ensures that the proper mix of rock, clay and fines are present in the material mix. Overtime, gravel is separated though heavy vehicle traffic pounding, environmental conditions (rain, snow, etc) and aggregate loss.

Fresh gravel is always valued, however, new aggregate is not necessary. If surface material can be bladed to a depth of 1.5– 2.0 inches fresh aggregate is not needed, but it does ensure the application will last longer and that the proper mix is established.
