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 choice between asphalt and concrete depends on your priorities, budget, and climate.

Concrete is generally more durable, lasting up to 50 years with minimal upkeep, and offers more customization options like staining and stamping, which can add more to a home's value. However, it is more expensive upfront and can be prone to cracking in cold climates where water can freeze and expand.

Asphalt is typically cheaper and quicker to install and is easier to repair. It performs better in colder climates. However, it requires more maintenance, including regular resealing, has a shorter lifespan, and can get hot and sticky in intense sunlight.

Ultimately, if durability and long-term value are key, concrete is often the better choice. If upfront cost and performance in cold weather are more important, asphalt may be preferable.

Since it has a smoother surface using a mixture of finer rock and sand, 41A tends to be the best asphalt grade for a driveway, especially for residential driveways. Other options are available, but more homeowners choose 41A for a smoother asphalt driveway. Talk with your asphalt driveway professional for recommendations of the best grade for your specific driveway.

Concrete is typically the best material for a driveway if you’re looking for longevity, cost-effectiveness, and ease of maintenance. But, it’s not ideal for areas with annual freeze-frost cycles, nor is it the most attractive option—although you can get it stamped or painted. If your location is consistently below freezing, asphalt may be a better choice.
