To calculate the asphalt driveway cost, you just need to take a measurement of length x width to get the approximate square foot area, and multiply it by the average cost of $3-$4/square foot. Example: A driveway thatâs 10â² wide and 60â² long equals 600 square feet. 600 x $3-$4 = $1,800-$2,400 (estimated asphalt driveway cost) At that approximate cost, a driveway contractor will dig out 4-6 inches of whatever you already have in place, replace it with clean driveway gravel and grade it to a level and compacted surface.
The average price to haul away an old asphalt driveway and replace it with a new one is around $5,000, based on several factors. âTypical life expectancy of an asphalt driveway is 15 years,â says Ron Reibling, owner of Aurora Asphalt & Sealcoating in Champlin, Minnesota.
