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.
