Recycled asphalt is not better than gravel, but can be a good alternative. It is inexpensive, but not as low-cost as gravel, and doesn’t tend to last as long. Recycled asphalt isn’t as dusty as gravel and is more environmentally friendly. The black look can be something that homeowners prefer. No matter what, ensure you choose an experienced recycled asphalt contractor. 

An asphalt overlay or top coat costs between $3 and $7 per square foot. For a standard, single-car driveway that’s 10 feet wide and 20 feet long, that’s a total of between $600 and $1,400. For a two-car driveway, you’re looking at a total of between $1,200 and $3,000.

The answer to whether or not you need to get a permit before you start your driveway can vary widely based on local ordinances and the scope of your driveway ideas. In most urban and suburban areas, a permit is needed before building a new driveway to ensure that a homeowner is using safe materials and proper drainage practices while designing and constructing a new driveway. In some rural areas, a homeowner may not be required to apply for a permit. When building a new driveway on your own, always check with your local building department to see if you need to request a permit. When hiring a driveway contractor, verify that the right permits are being used before driveway construction begins.

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.
