As winter approaches, property owners in colder climates need to be mindful of the toll that harsh weather can take on asphalt and concrete surfaces. Snow, ice, and freezing temperatures can accelerate wear and tear, leading to costly repairs if not addressed. At Metro Paving, we believe proactive maintenance and understanding the risks of winter weather can save you time, money, and stress. Here’s how winter affects your pavement and what you can do about it.
1. Freeze-Thaw Cycles Cause Cracking
One of the most common culprits of winter damage is the freeze-thaw cycle. When water seeps into small cracks in asphalt or concrete and freezes, it expands, forcing the cracks to widen. As temperatures fluctuate, this repeated freezing and thawing can weaken the structure of your pavement, leading to more significant damage like potholes.
2. De-Icing Chemicals and Salt Can Erode Surfaces
While necessary for safety, de-icing chemicals and salt can accelerate deterioration. Salt can penetrate the surface of concrete, causing spalling (surface chipping) and weakening the material. In asphalt, salt can exacerbate small cracks and allow water to penetrate deeper, compounding the effects of freeze-thaw cycles.
3. Heavy Snow Removal Equipment Adds Stress
Snowplows and heavy snow-removal machinery can damage already weakened asphalt and concrete. Scraping can loosen chunks of pavement or exacerbate cracks, especially in areas that weren’t properly sealed before winter.
4. Moisture Retention Leads to Long-Term Damage
Snow and ice that remain on the surface for long periods can seep into tiny cracks and pores, saturating the pavement. This trapped moisture can freeze and expand, causing further cracking and destabilization.
5. Concrete Is Susceptible to Scaling and Frost Heaving
Concrete surfaces, especially older ones, are prone to scaling, where the surface flakes off due to freeze-thaw cycles. Frost heaving, where the ground beneath the concrete expands and lifts the surface, can also cause uneven or broken sections.
Preventative Measures for Asphalt and Concrete in Winter
- Seal Cracks Before Winter: Applying crack sealant before temperatures drop prevents water from seeping in and causing damage.
- Use Non-Corrosive De-Icing Products: Opt for products designed to be less harsh on pavement surfaces, such as calcium chloride.
- Schedule Regular Maintenance: Have your pavement inspected annually to address small issues before they become significant.
- Clear Snow Promptly: Removing snow and ice reduces the risk of prolonged moisture exposure.
By taking preventative steps and addressing issues early, you can protect your investment and extend the lifespan of your asphalt or concrete. Contact Metro Paving for expert advice and services to keep your pavement in top shape year-round.
