• Magnesium Chloride, is produced from naturally-occuring minerals in the Great Salt Lake.
• It is hygroscopic ( attracts moisture) to provide maximum control of dust.
• Designed for deep soil penetration to create compact, smooth road surfaces.
• Is an effective dust control and soil stabilization product with minimal environmental impact.  DustGuard is used in several environmentally sensitive areas such aas U.S National Forest roads.

Advangages  

• Maximum cost effective slolution for dust control and road base stabilization for roads with normal size and particle distribution. 
• Proven performer for large commercial operations, private industry, military and the government agencies.
• Effective in high and low humidity conditions
• Non-toxic and safe for environment.
• Reduces the need for blading, watering and gravel replacement
• Provides a smooth, firm driving surface which increases vehicle productivity, decreases fuel consumption and saves time.
• Prevents costly soil erosion caused by destructive wind conditions.
• Reduces the cost of cleaning vehicles, equipment property, vegetation and living sites.
• Reduces replacement expenses of light duty truck windshields by controlling gravel spray in busy yard locations.

Improve Safety

• Improve visibility, reducing the chance of accidents
• reduces the chance of injury from flying stones and loose gravel around the work site.
• Provides cleaner air, cleaner vehicles and cleaner homes.
• Promotes better health and fewer complaints.

Preparation & Application

Road Surface Preperation:

• If the surface is pemeable, smooth frim and shaped for drainage, it's ready for application.  Before applying DustGuard make sure ruts, wasboards, potholes, drainage problems, gravel segregation and hard, impervious areas have been rectified.  Correct sufrace preperatio is very important to the overall success of the DustGuard treatment.

Blading:

• Blading will take care of problems like ruts and potholes, and provide a smooth, well drained surface.  Blading is not necessary if the surface is already smooth, shaped and evenly mixed.

Compacting:

Blading loosens the surface, it should be watered and compacted to restore a dense, tight surface

Pre-watering:

Before applying DustGuard the road should be watered; ideally to a depth of 3 - 4 inches to break the surface tension and allow maximum penetration, it should be bladed and re-compacted, creating a firm but easily penetrated surface.

Disadvantages

• To maximize effectiveness for Magnesium Chloride.  Road base material should have adequate clay fines.
• To much clay in road base can cause base to hold excessive water.

Application

• Professionally applied by factory trained specialists.  Application can be made with existing equipment.

Appearance

• Clear to slightly yellow, odorless liquid.  Road surface will initially appear moist, then gradually appear to dry.

The relative effectiveness of commercially available road dust suppressants in abating fugitive dust emission and loss of fines from unpaved road surfaces wass assessed in a field based research project.  The dust supperssants studied, lignin derivatived and chloride based compounds, were used on unpaved road test sections during the severe dusty months (late spring to fall).

To measure the relative effectiveness of the different dust suppressants, comparative fugitive dust emission studies wre conducted on several unpaved road test sections using  a dust sampling device developed in this research.  In addition total aggregate loss from the surfaces of the test sections was measured.  Based upon the prevailing costs, analyses were performed to determine the economics of using the different dust suppressants.

While unpaved roads carry a small portion of the nation's traffic, they provide a vital first link in the nation's economy.  Of the nearly 4 million miles of road network in the continental U.S. it is estimated that about 65% are unpaved.  One major problem associated with unpaved roads is traffic generated fugitive dust.  To residents living along unpaved roads, the airborne dust penetrates their homes causing nuisances and health problems such as hay fevers and allergies.  The fine suspended dust particles contribute significantly to the particulate matter loading in the atmosphere.  According to air pollution studies, nearly 34% of the particulate matter in the atmosphere originates from unpaved roads nation wide, making unpaved roads on of the major man-made sources of fugitive dust. In addidion to environmental degradation, the generation of dust means loss of aggregate and subsequent road surface deterioation as the loss of road surface fines in the form of dust leads to the formation of ruts, potholes and corrugations.  These conditions represent a significant material and economic loss.

• Dust measurement data indicat that there is a sustantial reduction in fugitive dust emission with application of chemical dust suppressants (50 - 70% reduction).
• With the Chloride compounds tests show less dust.
• Cost analysis showes a 30-46% reduction in total annual maintenance cost for treated test sections over the untreated sections.
