The average cost of a macadam driveway, as of 2015, is $1 to $3 a square foot for resurfacing the driveway or $2 to $4 a square foot for a brand new driveway. A new macadam driveway is about $1,200 to $2,400, depending on its size.
This does not include the cost of labor and installation, which adds to the final cost of the driveway. Most driveway contractors charge a base price for the entire project as opposed to a per square foot price. Additional fees are added for larger driveways and if a permit is required for the location. Permits are often required if it connects to a public street.
