Frequently Asked Questions
How wide should a driveway be?
A single-car driveway should be at least 10 feet wide, while a double-car driveway should be 20-24 feet wide. Add 2-3 feet if the driveway is next to a wall or fence.
How thick should a driveway be?
For residential driveways, a 2-3 inch thickness of asphalt over a 6-8 inch compacted stone base is standard. Heavy-duty applications may require 3-4 inches of asphalt.
How long will a new driveway last?
With proper installation and maintenance, an asphalt driveway typically lasts 15-20 years. Regular sealcoating every 2-3 years can extend its lifespan significantly.
