Asphalt and concrete driveways both crack, and for the same reasons. Often, asphalt driveways are set up as a long surface, and may crack more easily than concrete for this reason. Additionally, the controlled joints in concrete driveways can assist in reducing cracking. Both materials are great for driveway construction, and regardless of the material you choose, large cracks should not occur for at least several years.
Asphalt vs. Concrete
SIGNS OF CRACKS IN DRIVEWAY
Tell-tale signs of cracks in your driveway (aside from the crack itself) include weeds popping up and anthill mounds spilling out of the crevices. While unsightly and annoying, small cracks are considered non-structural. Cracks with wider openings or heaved edges must be repaired, as they are a definite trip hazard.

WHAT ARE CAUSES OF CRACKS IN A DRIVEWAY?
CONCRETE AND ASPHALT PROPERTIES
Concrete driveways are constructed with a light gauge steel mesh embedded in the slab when the concrete is placed. Additionally, glass, steel, or plastic fibers can be added to concrete mix for improved tensile strength. Asphalt is susceptible to all of the same conditions as concrete. Asphalt also tends to crumble at the edges as it deteriorates.
REPAIRING A CRACKED DRIVEWAY
So what qualifies a crack as large enough to require this service? Any change in surface larger than a half-inch is considered a trip hazard.
