The dimensions of a driveway apron vary based on local building codes, the width of your driveway, and the distance between the driveway and the road. On average, aprons range from 12 to 24 feet wide and 8 to 18 feet long. Typically, the end of the apron connected to the driveway matches its width—such as 10 to 12 feet for a single-car driveway—while the end at the street flares out to allow cars to turn in and out more easily. In some areas, you may not be responsible for the portion of the apron that extends beyond the sidewalk, but this depends on local laws.

Yes, recycled asphalt driveway costs can be substantially lower than new asphalt. With new asphalt costing between $90 and $190 per ton, this option can cost as much as 10 times more than laying down asphalt millings.

The average cost of 1,500 square feet of asphalt ranges from about $10,500 to $22,500, depending on location, thickness, base material, and how accessible the job site is to crews and equipment. Keep in mind that your asphalt material cost may vary depending on its type, ranging from porous asphalt to heated blacktop. Standard asphalt costs $7 to $13 per square foot.

Cobblestone is just one of many driveway materials. Other, more economical, albeit less elaborate options include concrete, asphalt, and gravel. 

If you want a material that most closely resembles cobblestone, your best option is bricks or pavers. Both cost anywhere from $10 to $50 per square foot and can be laid in all kinds of patterns. Depending on the type of paver you choose, you can also get a good bang for your buck by investing in durable natural stone.
