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.

The cost to pour a driveway apron depends on the material and size. Concrete costs $3 to $10 per square foot, asphalt ranges from $2 to $5, and pavers are $5 to $15 per square foot. Additional expenses, like excavation, base material, and labor, can increase the total cost. For example, a standard 12x15-foot concrete apron could cost between $540 and $1,800, depending on local rates and additional work required. Always consult a local driveway paving contractor to get an accurate estimate tailored to your project.

Gravel is the most economical and least expensive driveway material, costing between $1 and $3 per square foot. This is significantly cheaper than alternatives like asphalt or concrete. However, it's important to consider long-term costs, as gravel driveways require regular maintenance. You will likely need to add new gravel filling once or twice a year and regularly rake it to keep it level, which can add to the overall cost over time.

If your driveway is cracked, you can repave it with a process called asphalt overlay. Overlay is more cost-effective than a full replacement but is better suited for minor cracks and issues. If you have major cracks or other problems like water pooling, asphalt overlay isn’t your best bet. Plus, paving over a cracked driveway only extends the lifetime by about 10 years, whereas replacing it would start the clock over completely to give you up to 30 years.
