As a very loose guideline, in most areas, asphalt installation will range from about $2.50 to $4.00 per square foot, while concrete typically ranges from about $4.00 to about $6.00 per square foot but can rise to more than $15.00 per square foot when special finishes and detailing are used.
A concrete driveway 90 feet long and ten feet wide would be around $1800 for materials plus an additional $2000 or so for labor, for a total cost of nearly $4000. Asphalt driveway paving costs $2-$6 per square foot installed. For a 500 square foot (50 x 10) driveway this works out to an average cost of $2500. A Macadam driveway, also known as tar and chip, consist of crushed stone or gravel sprayed with liquid asphalt. They cost around $2-$5 per square foot. Another option is a cobblestone driveway.
