New asphalt goes through two stages: drying and curing. Drying typically takes 24 to 72 hours, after which the surface is solid enough for light use like walking or careful driving. While you may be able to park on it after 72 hours, the surface is still soft and should be treated gently. Full curing is a much longer process, taking anywhere from 30 days to a full year for the asphalt to reach maximum strength. During this extended curing period, the asphalt is susceptible to damage from heavy vehicles, sharp objects, and high temperatures. Factors like weather, the specific asphalt mix, and application thickness all influence drying and curing times. For the most accurate timeline and to ensure the longevity of your new asphalt, it is always best to consult with your installation contractor for their specific recommendations.

The decision to repair or replace your driveway depends on the extent of the damage. If your driveway has a few small cracks, a simple repair will do the trick. If you see larger cracks and potholes, it may be time to consider resurfacing or replacement. Resurfacing is a great option if more than 25% of the surface is damaged, but if the damage is extensive—deep cracks or significant sinking—it’s best to replace the driveway entirely. A new driveway, with proper care, can last decades while patching or resurfacing might only hold up for a few years before needing more attention.

In most cases, you don’t need a permit to repave your driveway, although some exceptions exist. If you’re widening your driveway and plan on widening the apron as well, you’ll usually need a permit from the Department of Transportation in your area. This permit costs between $50 and $300 in most cases. Most municipalities will also require a certified and insured contractor do the work relating to the apron and curb cut. You can contact your building department or ask your paving company if you need a permit. Your driveway professional will usually pull the permit for you.

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.
