Why Do Asphalt Driveway Cracks Happen?
Understanding why cracks form can help you protect your asphalt driveway from common stressors. Here are the top reasons:
- Weather Conditions: Extreme temperatures can make asphalt expand and contract, leading to cracking over time.
- Heavy Traffic: Constant pressure from vehicles, especially heavy ones, can strain the asphalt, eventually causing cracks.
- Aging: Over the years, asphalt loses some flexibility, making it more prone to cracking as it ages.
Practical Tips to Prevent Asphalt Driveway Cracks
Preventing cracks before they start can save you time and money. Here are some straightforward tips to help protect your asphalt driveway:
- Sealcoat Regularly
Applying a high-quality sealant every 2-3 years provides a protective layer that shields your asphalt from moisture, sunlight, and everyday wear. - Ensure Proper Drainage
Make sure your driveway slopes correctly to direct water away from the surface, preventing pooling and potential damage. - Avoid Heavy Loads
Limit the weight of vehicles parked on your driveway, especially during hot weather when asphalt softens and is more vulnerable to stress.
How to Repair Cracks in Your Asphalt Driveway
If cracks do appear, it’s best to repair them quickly to keep them from spreading. Here’s a simple process to help you repair cracks effectively:
- Clean the Crack
Remove any dirt, debris, or vegetation from the crack with a screwdriver or a similar tool. A clean crack allows the filler to adhere better. - Choose the Right Filler
Select a filler suited to the crack size. Different products are available depending on the crack width and repair needs. - Apply the Filler
Follow the instructions on the product. Typically, you’ll fill the crack, smooth it out, and allow it to cure based on the manufacturer’s guidelines.
