Asphalt is a highly durable material for driveways, parking lots, and roads, but it is susceptible to weather-related damage. Learn how extreme temperatures can affect your asphalt and how you can protect it from costly repairs.
What Makes Up Asphalt?
Asphalt is made up of two essential components: aggregates and binder.
-
Aggregates: These are made up of crushed stones, gravel, sand, and minerals. Aggregates make up about 95% of the composition of the asphalt and give it strength and stability. The size of the aggregates varies depending on the application, such as larger stones for high-traffic roads and smaller ones for residential driveways.
-
Binder (Asphalt): The sticky substance that holds the aggregates together. Asphalt, refined from crude oil, helps maintain the structure and integrity of the pavement.
How Weather Affects Asphalt
While asphalt is tough and built to endure, it is still vulnerable to extreme weather conditions.
Heat:
Continuous exposure to high temperatures can cause the asphalt binder to soften and weaken. This leads to cracking and other forms of damage, reducing the lifespan of the pavement.
Cold:
In cold weather, snowmelt and rainwater can seep into existing cracks, freeze, and expand. This freeze-thaw cycle puts pressure on the pavement, making it more prone to cracks, potholes, and crumbling over time.
Tips to Protect Your Asphalt from Weather
-
Seal Cracks Early:
Catching cracks early and filling them prevents moisture from seeping into your pavement, avoiding further deterioration. For smaller cracks, liquid filler is fine; for larger cracks, a hot pour rubberized filler is ideal, especially for commercial properties. -
Fix Potholes Quickly:
Potholes are more than just unsightly; they’re dangerous and can worsen over time. Patching them prevents water infiltration and further damage. -
Use Safe Deicers:
When choosing deicing products, opt for sodium chloride or calcium chloride. These are less likely to damage the asphalt than other options. Avoid overuse, as even these can cause harm if applied too frequently. -
Check for Standing Water:
Water pooling in certain areas can cause lasting damage to asphalt. After rain or snowmelt, inspect your driveway or parking lot and address any standing water promptly. -
Clear Snow Promptly:
Snow can cause damage over time if left on the surface. Use snow removal tools to keep your asphalt clear and prevent stress on the surface. -
Seal the Asphalt:
Applying an asphalt sealant is like giving your pavement a protective shield. It blocks moisture and UV rays, helping to extend the life of your asphalt.
