Road Dust Suppression

How to keep dust down on unpaved roads (gravel roads, crushed concrete roads, dirt roads and soil based roads)

dust suppression

When a roads (or construction sites) have a dust problem, there is multiple options to solve your problem. Lets get your dust issued solved quickly. The following page  explains the benefits to keep dust down on roads. Additionally we cover Corestone’s solutions to dust, soil stabilization and other unpaved road solutions.

Benefits Of Road Dust Suppression

1 – Improve Air Quality
Air quality is a huge reason for dust control. And it’s a big deal to government entities. When the air is clear, you can see further, and your neighbors wont regret your dusty road or job site.

2 – Safety
A dusty road can create an unsafe working environment. As dust distracts and clogs the air, it can clog your safety efforts.

3 – Improve Visibility
As dust circulates in the air, your ability to see decreases. Dust can enter the eyes and cover your vehicle’s vision. Less dust in the way of your vision, will help you see clearly.

4- Save On Water
Water trucks are commonly used to slow dust problems. But water evaporates quickly and the cost continues. Water is not free and over time, it can add huge cost to your bottom line.

5- Decrease Maintenance Cost on Equipment
Dust causes problems to engines and vehicles. This creates a consistent need for maintenance that can easily be avoided with dust suppression.

6 – Prevent Dust-related Illness
Dust in the lunges can create a negative health effect over time. Its best to keep your air and lunges clear.

7 – Avoid Fines from Government Agencies
Dust control is highly regulated. It only takes one fine, to consider road dust control a top priority. Don’t wait.

Solutions For Road Dust Control

1 – Topical solutions
Topical applications are applied to the surface of the subject area. For best results apply evenly with pressurized spray equipment, distributor trucks, spray trailers, or hand sprayers.Allow 24 hours for material to set before resuming traffic.

Dust Control Material Types:

Polymer based: We use a Synthetic polymer emulsion concentrate consisting of a combination of carefully selected polymers designed specifically for dust palliative and soil stabilization applications.  It is safe, non-toxic and environmentally friendly.  Provides superior bonding and stabilizing for lasting performance.

Calcium Chloride: Calcium chloride (CaCl2) is a hygroscopic salt that draws moisture from the air to form a solution in road gravel that keeps road surfaces constantly damp, even in hot, dry conditions. The moisture helps to bind particles together to create a hard and compact road surface. Because it penetrates several inches into the road base, calcium chloride also contributes to overall road surface stability.

Magnesium Chloride: Magnesium chloride (MgCl2) is also a hygroscopic salt. It is most commonly supplied in liquid form at a concentration of about 30%. Liquid magnesium chloride and liquid calcium chloride exhibit similar water attraction properties. However, under hot, dry conditions, CaCl2 remains liquid, while MgCl2 does not, resulting in lower dust suppression capabilities under these conditions. Application rates and environmental profiles of the two materials are very similar.

2 – Added depth soil stabilization
The process of added depth soil stabilization is as follows. Scarify, till or loosen dirt or gravel surface to a depth of 3 to 4 inches.  Apply material with pressurized spray equipment.  Two applications my be required to achieve recommended coverage rate.  A grader may be used to level material prior to compacting with a roller.  Once material has been rolled, a light application of material should be sprayed over the surface as a final lock down coat.

3 – Full Cement/Lime Stabilization

Soil Stabilization is the alteration of soils to enhance their physical properties. Stabilization can increase the shear strength of a soil and/or control the shrink-swell properties of a soil, thus improving the load bearing capacity of a sub-grade to support pavements and foundations.

Soil Stabilization can be utilized on roadways, parking areas, site development projects, airports and many other situations where sub-soils are not suitable for construction. Stabilization can be used to treat a wide range of sub-grade materials, varying from expansive clays to granular materials. This process is accomplished using a wide variety of additives, including lime, fly-ash, and Portland cement. Other material byproducts used in Stabilization include lime-kiln dust (LKD) and cement-kiln dust (CKD).
