Fortunately, the tar and chip method provides a reasonably priced, eye-appealing way to seal driveways with low cost long-term maintenance. Tar and chip paving combines asphalt and stone to create a textured, hard surface. The end result is a driveway that provides more texture than plain asphalt and better traction in slick conditions.
