Dust Control & Road StabilizationClements Fluids Management, LLC

Why Roadmaster™ Calcium Chloride?

• Provides dust control at lowest total cost.

• Improves road quality by providing stabilization.

• Reduces total road maintenance costs.

• Provides a real return on investment.

• Proven technology for over 70 years.

How does Roadmaster™ Calcium Chloride Work to Control Dust?

• Roadmaster™ Calcium Chloride is a clear, odorless solution that can easily be applies year round.

• It coats the fines particles in the road as well as the aggregate causing increased cohesion, allows high-density compaction and improved durability of the surface.

• It’s hydroscopic property allows it to draw moisture from the atmosphere and soils thus resisting evaporation for long periods.

• It is deliquescent and uniformly penetrates the roadway surface with much less tracking than lignosulfonate.

How Roadmaster™ Calcium Chloride Works to Stabilize

• Keeps fines in place.

• Fines are the cementing materials for the aggregates of the unpaved surface and base.

• Provides cohesiveness by adding to surface tension of water for greater density.

• Maintains optimum moisture.

• Facilitates maximum density by compaction.

• Provides frost protection.

• Lowers freezing point of water.

• Reduces voids.

• Controls moisture content.

Benefits from Dust Control with Roadmaster™ Calcium Chloride

• Saves money compared to alternatives.

• Eliminates watering / reduces application frequency.

• Less overall road maintenance by reducing rock loss and frequency of balding.

• Reduces equipment wear and maintenance.

• Safety through better visibility.

• Increases comfort of workers and residents.

• Eliminates health hazard posed by dust.

• Safely increases travel / haul productivity due to maintainable speeds.

• Environmentally kind / safe.

Benefits From Stabilization with Roadmaster™ Calcium Chloride

• Safer & better quality surfaces.

• Reduced road maintenance costs.

• Less aggregate loss.

• Fewer bladings.

• Fewer spot repairs.

• Less frost damage.

• Reduction on the overall wear and tear of all equipment used to maintain the road as well as any vehicle that travels the road.

• Example: blade wear, tire wear, filters and shocks.

• Fuel and man-hour savings on re-work.

Roadmaster™ Calcium Chloride Beats All Alternatives on both Performance and Price

• Water

• Waste Brines

• Mag Chloride

• Lignosulfonate

Roadmaster™ Calcium Chloride compared to Water

Roadmaster™

• Infrequent and less costly total applications.

• Moisture held in road to retain fines and aggregate.

• Road stabilized for long life.

Water

• Frequent applications which are equipment and labor intensive.

• Dampens road surface temporarily then quickly evaporates and dust returns.

• Road continues to deteriorate and is never stabilized.

Roadmaster™ Calcium Chloride compared to Magnesium Chloride

Roadmaster™

• Remains a solution at much higher temperatures and low relative humidities thus resisting evaporation on hot, dry days.

• Less Roadmaster™ required per application. Also less frequent applications.

• Manufactured to ASTM specifications. Shipped and available in higher concentrations.

Magnesium Chloride

• Similar to CaCl, but begins to lose the ability to attract moisture and resists evaporation at temps lower than 72 deg F.

• Independent studies show equal dust effectiveness requires 18% more MgCl per unit area.

Roadmaster™ Calcium Chloride compared to Lignosulfonate

Roadmaster™• Less Expensive.

• Good surface traction.

• Easy equipment clean up and little surface tracking.

• Dense, thicker stabilized road.

• Less frequent application required since it remains active and retains moisture.

• Can be bladed as required.

Lignosulfonate

• Expensive.

• Surface slippery when wet.

• Gums up equipment and tracks.

• Potholing and cracked crust.

• Short life, repeated applications.

• Cannot be bladed without breaking up.

Roadmaster™ Calcium Chloride compared to Waster Brines

Roadmaster™

• Manufactured under quality control and meets ASTM specifications.

• Infrequent applications.

• Binds fines and aggregate with moisture taken from air and soil.

• CaCl is necessary to vegetation and soil.

• Less chlorides in environment.

Waste Brines

• Byproduct / mixture of components.

• Low percentages of active ingredients requiring more frequent applications.

• Not hydroscopic – Short term effectiveness.

• Many brines are harmful to vegetation and soil.

• More chlorides in environment.

Environmental Review

Roadmaster™ Calcium Chloride offers far more benefits to the environment and personal health and safety than doing nothing at all to control dust.

• Air quality improvements far outweigh any environmental concerns.

• Roadmaster™ Calcium Chloride stays in the roadway. Estimated 5% lateral movement to shoulder.

• Roadmaster™ Calcium Chloride beneficial to vegetation. Both Calcium and Chloride are nutrients for crops.

Guidelines for Roadmaster™ Treatment of Unpaved Roads

• Cut grass on shoulders, pull ditches, scarify or cut out potholes where necessary and add new / required aggregate.

• When road has hard crust due to prior treatment from a petrochemical product, scarify to a depth ratio of 3 parts untreated soil to 1 part treated.

• Grade to a modified “A” Crown with slopes of ½ inch per foot with proper drainage of water.

• Apply Roadmaster™ Calcium Chloride surface application after grading.

• Compaction is accomplished by roller or normal traffic depending on the road materials.

Roadmaster™ Calcium Chloride Application Rates for Dust Control

Liquid Form

• 30-39% Roadmaster™ solution.

• Apply uniformly by applicator or water wagon.

• .36 gallons of 38% solution per square yard.

Conclusion

• Working with Roadmaster™ Calcium Chloride is very routine, without the need for any unusual equipment.

• Application is simple.

• Easily adaptable to existing road maintenance programs.

• Provides dust control at lowest total cost.

• Improves road quality by providing stabilization benefits.

• Reduces total road maintenance costs.

• Increases safety.
