Dust Management Services

Dust management services incorporate one or more measures for dust control. Depending on source of dust, efficiencies of different solutions vary.

Dust source can be point or diffuse source. Examples of point sources of dust are woodworking machines, grinding machines, industrial smokestacks, etc. Large scale sources are construction and demolition sites, mines, quarries, unpaved surfaces, piled loose materials etc.

For small scale sources the efficient dust control can be achieved through use of filters, vacuum systems, partitions or combination of these. However, for diffuse sources this kind of dust management services cannot be applied.

The role of wind fences is to reduce wind velocity around dust sources and thus decrease rate of dustiness. This solution is quite expensive due to need for large amount of ex situ materials, complex installation and demanding maintenance. On the other side wind fences decrease dust generation to some extent and if source is large area, they are quite inefficient.

Very common are wetting methods for dust control which include an adequate and continuous supply of water and application by suitable water sprays or jets. This method can be applied on various dusty sites but is very temporary due to evaporation. Therefore, this kind of dust management services requires frequent reapplications. It is not very convenient for driving surfaces since it doesn’t contribute to road stability and consequent road deformations occur during time due to vehicle and machinery load. Wetting of driving surfaces is not practical in regions with below-freezing outdoor temperatures.

Many companies which provide dust management services consider slower vehicle movements as one of necessary measures to reduce dust generation in case of unpaved driving surfaces such as haul and public roads. This measure also slows down work activities negatively influencing economic efficiency. Global Road Technology offers a range of dust control products which fulfil different needs related to different purposes, soil types and weather conditions.

For treatment of driving surfaces GRT suppressants with binding properties can be used to form stable matrix and increase water resistance of soil body. Through use of GRT dust management services not only efficient dust prevention is achieved but also high quality driving surfaces can be created. GRT doesn’t consider decreased vehicle velocity as necessary compromise. Shown through case studies improvement of rolling resistance of unsealed roads through use of GRT suppressants can be 15%. If compared to the rolling resistance of conventional sprayed chip seal surfaces, results showed that GRT treated roads are of the equivalent or slightly better quality. Achieved improvement of friction level can be 100% when GRT dust management services applied.

GRT methods require only a small amount of water which also reduces need for associated transportation and labour.

Additionally, GRT roads require no grading, while other dust management services incorporate grading three to four times a month. Effects of GRT treatment last for months and GRT products provide a cumulative effect, which means that each new application lasts longer than all previous applications of the product.
GRT dust management services provide highly durable roads that will not break down easily from UV-rays, enzymes, and soil microbes nor wash away in the rain. As a result, your monthly road expenses decrease to more manageable levels while work efficiency and safety increase.

Beside specialized products for driving surfaces, Global Road Technology offers products for preventing dust from piled loose materials at construction and demolition sites, mines and quarries or materials that are being transported. These products coat particles of piled materials without changing their properties.

Summarized benefits of using GRT dust management services:

• Prevented dust
• Protected workers and nearby residents
• Reduced rolling resistance
• Improved friction properties
• Improved productivity and traffic flow
• Reduced need for road maintenance
• Saving water
