Most driveways in this area are asphalt. They are common here because of our freeze-thaw cycle. If your driveway was installed properly and the drainage is good, your driveway should last between 20-25 years, especially if the driveway was sealed every few years in the fall. The amount of traffic your driveway sees, and the weight of vehicles using it, also contribute to its lifespan.
Eventually, though, a driveway will need to be replaced. But how do you know when?
