Asphalt Parking Lot Removal: What to Expect
There are two ways to remove asphalt: with heavy, powered equipment or by hand with basic tools. Because parking lots are so large, they are removed using big, heavy equipment to get the job done efficiently. Asphalt removal tools include excavators, backhoes, as well as circular saws and/or jackhammers in some cases.
