Road dust suppression


Measures to prevent dust accumulation on roads are necessary to ensure safe tire grip. The roughness of the surface and the elastic materials of the treads of tires allow the wheels to be pressed into the surface and adhere to the road. This ultimately guarantees safe driving. Poor contact with the road occurs if a layer of dust settles on a dry road surface.Road grip is reduced by two or three times and sometimes is comparable to driving on slippery ice.

Dust formation often occurs on unpaved roads or on roads covered with gravel. Dust is often found on roads near active buildings construction sites or in quarries. Dusty clouds limit the view for the driver and passengers and clogs air filters.

Zirax Calcium Chloride for road maintenance.

The presence of dust depends on the compaction of the soil, which is significantly reduced if the coating does not contain enough moisture. Calcium chloride is able to retain moisture, keeping the soil dense enough to prevent dust formation and adds strength to the road surface. Calcium Chloride reduces gravel loss by 80 percent, helping to reduce vehicle owners’ dissatisfaction with dust and uneven road surfaces.

Calcium Chloride is used as follows:

  • To grade the road surface to the depth of the largest pothole.
  • Zirax Calcium Chloride for road maintenance.

  • The road profile is formed up to 4% of the ridge cross-section.
  • Zirax Calcium Chloride for road maintenance.

  • A 29-38% calcium chloride solution is sprayed evenly by a pressurized spray system
