Questions & Answers About Asphalt Paving & Sealcoating
Frequently Asked Questions
How long does asphalt paving last?
Asphalt paving can last 15-30 years, depending on factors like installation quality, climate, traffic load, and regular maintenance. Properly maintained asphalt—through sealcoating, crack repairs, and routine care—can significantly extend its lifespan.
How long does it take for new asphalt to cure?
Freshly paved asphalt is ready for light foot traffic within 24 hours but takes 48-72 hours to handle vehicle traffic. However, a full cure (complete hardening) can take 6-12 months, during which time the surface may be softer and more vulnerable to damage.
What is the difference between asphalt and concrete paving?
- Asphalt is more cost-effective, flexible, and quicker to install, making it less prone to cracking in cold climates.
- Concrete is more expensive, lasts longer but can be more susceptible to cracks from freezing and thawing.
Asphalt is often preferred for driveways, parking lots, and roadways due to its durability, affordability, and ease of repair.
How often should asphalt be sealcoated?
Sealcoating should be applied every 2-3 years to protect the asphalt from UV rays, water damage, chemicals, and general wear. New asphalt should be sealed 6-12 months after installation to allow proper curing before application.
Can asphalt be repaired, or does it need to be replaced?
It depends on the extent of the damage:
✔ Minor cracks & potholes – Can be patched or filled to prevent further deterioration.
✔ Worn or slightly damaged surfaces – May require resurfacing (overlaying new asphalt over the existing layer).
✔ Severely damaged or aged asphalt – May need complete replacement to ensure long-term durability.
What causes asphalt to crack or deteriorate?
Several factors contribute to asphalt damage, including: - Water infiltration & poor drainage
- Freeze-thaw cycles (expansion & contraction)
- UV exposure (oxidation causes brittleness)
- Lack of maintenance (unsealed cracks allow water damage)
Proper sealcoating, crack filling, and drainage solutions help prevent early deterioration.
How thick should asphalt be for a driveway or parking lot?
- Residential Driveways: 2-3 inches of asphalt over 4-6 inches of compacted stone base.
- Commercial Parking Lots: 4-6 inches of asphalt over 6-8 inches of compacted base.
- Roadways & Heavy-Duty Areas: 6+ inches of asphalt, depending on expected traffic load.
A strong base layer is just as important as asphalt thickness for long-term durability.
How soon can I drive on freshly paved asphalt?
You should wait at least 24-48 hours before driving on new asphalt. Heavy vehicles, trailers, and sharp turns should be avoided for at least a week to prevent indentations and scuff marks.
How much does asphalt paving cost?
The cost of asphalt paving varies based on: - Size of the project (square footage)
- Thickness of asphalt & base layers
- Site preparation (grading, removal of old pavement, etc.)
On average, asphalt paving costs $3-$7 per square foot, but obtaining a custom estimate is best for an accurate price.
What are the benefits of asphalt over other paving options?
✔ Cost-effective – More affordable than concrete.
✔ Quick installation – Driveable in 48-72 hours.
✔ Durable & flexible – Withstands freeze-thaw cycles better than concrete.
✔ Easy to maintain – Sealcoating and minor repairs help extend lifespan.
✔ Smooth surface – Safer for driving and reduces vehicle wear-and-tear.
How can I maintain my asphalt to make it last longer?
- Fix cracks & potholes immediately
- Ensure proper drainage to prevent water damage
- Avoid heavy vehicles on edges of driveways
-
Keep it clean from oil, fuel, and chemical spills
