If you've lived in Union or Essex County for even one winter, you know how quickly our weather can destroy asphalt. The good news? With proper maintenance and the right approach, you can minimize damage and extend your pavement's life by years.
The 5 Biggest Winter Threats to Your Asphalt
Understanding what damages asphalt in winter is the first step to preventing it:
1. Freeze-Thaw Cycles
critical riskWhat happens: Cracks expand up to 50% when water freezes inside
Prevention: Seal all cracks before first freeze
2. Rock Salt Damage
high riskWhat happens: Chemical deterioration of asphalt binder
Prevention: Use calcium chloride or sand alternatives
3. Snow Plow Scraping
moderate riskWhat happens: Surface scarring and aggregate loss
Prevention: Set plow blades 1/2 inch above surface
4. Ice Formation
high riskWhat happens: Creates slip hazards and liability issues
Prevention: Proper drainage and preventive treatments
5. Heavy Snow Load
moderate riskWhat happens: Can cause depressions in weak areas
Prevention: Remove snow promptly after storms
Pre-Winter Preparation Checklist
Complete Before First Freeze (Usually Early December)
Essential Tasks:
- Fill all cracks wider than 1/4 inch
- Apply sealcoat if due (every 2-3 years)
- Clear drainage systems and gutters
- Fix any ponding water issues
Smart Additions:
- Mark driveway edges with stakes
- Stock up on safe ice melt
- Schedule snow removal service
- Document current condition
Choosing the Right Ice Melt for Asphalt
Not all deicers are created equal. Using the wrong product is one of the fastest ways to damage your asphalt:
| Product Type | Works To | Asphalt Safe? | Cost | Our Take |
|---|---|---|---|---|
| Rock Salt (Sodium Chloride) | -5°F | No | $ | Avoid on asphalt |
| Calcium Chloride | -25°F | Yes | $$ | Best for extreme cold |
| Magnesium Chloride | -13°F | Yes | $$$ | Gentlest option |
| Sand/Grit | Traction only | Yes | $ | Good for light ice |
| Calcium Magnesium Acetate | 20°F | Yes | $$$$ | Eco-friendly choice |
Pro Tip: Make Your Own Safe Mix
Mix 3 parts sand with 1 part calcium chloride for an effective, asphalt-safe deicer that provides traction and melting power without the harsh chemicals of pure rock salt.
Snow Removal Without Damage
How you remove snow matters as much as when you remove it. Follow these guidelines to protect your asphalt:
DO: Best Practices
- • Remove snow within 24 hours of storms
- • Set plow blades 1/2" above surface
- • Use plastic shovels near edges
- • Push snow, don't scrape
- • Clear catch basins and drains
- • Apply ice melt before storms when possible
DON'T: Common Mistakes
- • Never use metal shovels on asphalt
- • Don't let snow sit for days
- • Avoid piling snow on asphalt edges
- • Don't over-apply ice melt
- • Never use hot water to melt ice
- • Don't ignore meltwater drainage
Month-by-Month Winter Maintenance
November
- Final crack sealing before freeze
- Clear all drainage systems
- Apply preventive ice treatments
- Mark driveway edges for plowing
December-February
- Remove snow within 24 hours
- Apply ice melt sparingly
- Check for new cracks monthly
- Document any damage for spring repairs
March
- Inspect for winter damage
- Schedule spring repairs
- Clean up residual salt/sand
- Plan sealcoating if needed
Understanding Temperature's Role
Critical Temperature Points
Freeze Point
Water in cracks begins expanding
Rock Salt Ineffective

Extreme Caution
Asphalt becomes brittle and prone to cracking
Emergency Winter Repairs
Sometimes damage happens despite your best efforts. Here's how to handle emergency repairs during winter:
Temporary Pothole Fix:
- 1Clean out loose debris and water
- 2Apply cold patch material in 2-inch layers
- 3Compact each layer thoroughly
- 4Overfill slightly to allow for compaction
- 5Schedule permanent repair for spring
Note: Cold patch is temporary. Professional hot-mix repair should be done when temperatures consistently exceed 50°F.
The Economics of Winter Maintenance
Prevention Costs (Annual)
- Fall crack sealing$300-500
- Safe ice melt products$100-200
- Professional snow removal$400-800
- Total Prevention$800-1,500
Repair Costs (If Neglected)
- Multiple pothole repairs$800-1,500
- Extensive crack repair$1,000-2,000
- Partial resurfacing$3,000-5,000
- Total Repairs$4,800-8,500
Special Considerations for Commercial Properties
Parking Lot Winter Management:
Legal Requirements:
- • Clear within 24 hours (most NJ municipalities)
- • Maintain ADA-compliant paths
- • Document all maintenance activities
- • Carry adequate liability insurance
Best Practices:
- • Pre-treat before storms
- • Zone plowing for efficiency
- • Designated snow storage areas
- • 24/7 monitoring during storms
Planning for Spring Recovery
Winter maintenance doesn't end when the snow melts. Plan these spring tasks now:
Spring Recovery Checklist:
- Full damage assessment (March)
- Power wash salt residue (April)
- Professional crack filling (April-May)
- Pothole repairs (April-May)
- Sealcoating if needed (May-June)
- Line striping refresh (June)
Pro Tips from 15+ NJ Winters
💡 "The biggest mistake? Waiting until you see damage. By then, water is already in the cracks, and the freeze-thaw cycle has started." - Randy Franco, Owner
💡 "Invest in good drainage. 90% of winter asphalt damage starts with standing water that freezes." - Mike, Foreman
💡 "Mark your driveway edges before the first snow. It'll save your lawn and prevent edge damage from plows." - Tom, Operations Manager
Winter Maintenance FAQs
Can I sealcoat in winter?
No. Sealcoating requires temperatures above 50°F for 24-48 hours to cure properly. In NJ, sealcoating season runs from May through October.
How soon after a storm should I remove snow?
Within 24 hours is ideal. The longer snow sits, the more likely it is to bond with the surface and create ice. Most NJ towns require clearing within 24-48 hours.
Is it better to use salt or sand?
For asphalt longevity, sand or calcium chloride-based products are better than rock salt. Rock salt is harsh on asphalt and should be avoided when possible.
Should I fill cracks in winter?
Only as an emergency measure with cold-pour products. Hot-pour crack filling (the permanent solution) requires warm, dry conditions. Plan for spring repairs.
Your Winter Action Plan
Protecting your asphalt through a New Jersey winter isn't complicated, but it does require planning and the right approach. The key is prevention: seal those cracks, manage water drainage, use the right deicing products, and remove snow promptly.
Remember, every dollar spent on winter maintenance saves $3-5 in spring repairs. Take care of your asphalt now, and it will serve you well for decades to come.
