Price variations can be caused by several different factors, such as:
- Site preparation.
- Ensuring adequate base is used and graded.
- Ensuring that adequate, evenly applied asphalt is laid.
For example: asphalt thickness might be 2.5 – 3 inches around the edges but only 1/2 an inch in the center. This makes the driveway appear to be the proper thickness to withstand harsh climate changes.
