How long can I expect my driveway or parking lot to last?

A good average to expect is around 20 years, as architects will typically design parking lots to last 20-25 years. Unfortunately, designs on paper vary from actual conditions and results can vary significantly. For structurally sound pavements that are experiencing isolated failures, a maintenance program that includes patching, sealcoating, and striping is recommended to help prolong the life of the pavement almost indefinitely.
