Road maintenance, de-icing & road traction in winter conditions
OPERATIONAL ISSUES RELATED TO ROADWAY MAINTENANCE DURING FREEZING CONDITIONS
Winter road maintenance operations require proven technical solutions to ensure safety, traffic flow and the performance of road networks exposed to freeze-thaw cycles. Municipalities, specialized contractors and infrastructure operators must deal with complex weather events: snowfall, freezing precipitation, refrozen ice or overnight frost. In this context, traction control, the ability to melt ice layers and the stability of applied treatments become decisive parameters for meeting service levels.
Sel Frigon offers a complete range of bulk solutions adapted to the specific needs of the road maintenance sector: de-icing salt, abrasive blends, treated compounds and formulations adjusted to established intervention plans.

Road maintenance, de-icing & road traction
Challenges related to roadway traction and ice management
Winter roadway traction depends on several factors: surface type, ground temperature, ambient humidity, previous salting, residual friction and average traffic. When a thin layer of ice forms on the surface, skid resistance is significantly reduced, increasing accident risks, maintenance costs and infrastructure wear.
Winter interventions therefore have two objectives: promote rapid melting of existing ice and prevent new ice films from forming.
Applied products must stay in place despite wind, traffic or mechanical movement. Treatment stability on the ground is an operational effectiveness criterion, especially on steep slopes, at intersections or in tight curves.
The choice of product, its gradation, treatment rate and compatibility with thermal conditions play a direct role in service quality.

Recommended products for road maintenance during winter periods
The products most frequently used for de-icing and improving road traction are:
- Bulk De-Icing Salt : standard dry sodium chloride salt, effective down to approximately -12 °C. It is the first line of intervention for paved roads.
- Anti-slip salt and sand mixture : an intermediate formulation used on secondary roads, ramps or low-speed urban zones. It combines melting action with immediate friction.
- Bulk treated and abrasive salt : salt treated with calcium chloride or magnesium chloride, enriched with an abrasive component. Used in critical areas, during intense cold or at identified trouble spots in the road network.
- Liquid chlorides (support application) : used in some cases for pre-wetting or post-storm maintenance.
Sel Frigon supplies all of these products in bulk, with consistent quality and custom formulation options.

Treatment planning according to service levels
Winter intervention plans establish different service levels according to road type, traffic, authorized speed and access criticality. Each level is associated with intervention timeframes, spreading thresholds and specific products. Dry salt is often reserved for priority 1 roads, while abrasive mixtures are used on connecting roads or residential segments.
Spreading frequency, treated strip width and dosage (e.g., 15 to 40 g/m²) vary according to temperature, precipitation intensity and residual conditions. Proper planning optimizes volumes, reduces losses and ensures consistent product use across the entire service area.
Products delivered by Sel Frigon are compatible with auger, chain or centrifugal spreaders used in municipal or private fleets. Consistent granularity and storage stability make them easier to integrate into pre-programmed mechanical cycles.

Bulk supply logistics and product storage
To meet winter plan requirements, products must be available in sufficient quantities and delivered within timeframes compatible with intervention windows.
Sel Frigon organizes deliveries according to actual needs, with options for advance reservation, direct site delivery or buffer storage in municipal depots. The product can be stored in domes, ventilated silos or on covered slabs.
Bulk conditioning maximizes storage space, reduces handling and limits risks associated with manual handling. Each lot is delivered with full traceability, a technical sheet and environmental compatibility information according to application zones. The approach is designed to adapt to remote regions, peak periods and field team priorities.
Logistics follow-up can be implemented for large municipalities or contract companies with several intervention sites.

Integration into winter road safety strategies
De-icing and traction-improvement products supplied by Sel Frigon fit into a broader strategy for securing winter travel. They complement mechanical operations (scraping, blowing, plowing) and help maintain acceptable traffic conditions between maintenance cycles. Their effectiveness helps reduce accidents, improve public service reliability and ensure access to essential buildings.
Municipalities and project owners can therefore build a structured winter response, with products adapted to each segment of the network. The use of calibrated salts and integrated abrasives ensures coherent continuity of action from intervention through to condition stabilization.
Technical choices validated with Sel Frigon account for durability, effectiveness, equipment compatibility and compliance with local environmental requirements.

Our FAQ
To learn more about our product
Which products are recommended for de-icing municipal roads in winter?
The most commonly used products are bulk de-icing salt, anti-slip salt-sand mixture and treated abrasive salt for critical areas or low temperatures.
What is the difference between dry salt and treated salt for road maintenance?
Dry salt is effective down to approximately -10 °C. Treated salt contains an agent (calcium chloride or magnesium chloride) that extends its effectiveness down to -25 or -30 °C and improves adhesion to the ground.
How do you determine the right spreading dosage in a municipal context?
Dosage depends on temperature, road type and priority level. It generally ranges from 15 to 40 g/m² for dry salt and can be adjusted using sensors or predictive models.
Can bulk-delivered products be used with all types of spreaders?
Can bulk-delivered products be used with all types of spreaders?
Should product choice be adapted to service levels?
Yes. Priority roads generally receive pure or treated salt. Secondary or residential roads use mixtures with sand or abrasive to ensure minimum safety at a controlled cost.
For more than two decades, Sel Frigon has handled shipload imports and de-icing salt distribution across Québec, supporting the operations of municipalities, industries, contractors and public institutions.
