An asphalt driveway is the least expensive and most durable paved surface a builder can install. If properly cared for, an asphalt driveway can last up to thirty years.
Asphalt driveways should not be sealed until they are fully cured and hardened, which takes a minimum of 90 days.
To ensure plenty of time for hardening, Askthebuilder.com recommends waiting six to nine months before sealing your new driveway.
Sealing your driveway before it is hardened and cured will mean that it is susceptible to imprints. Driveways that are sealed before they are ready also tend to crack and split which will lead to costly repairs.
When the time comes to seal your drive way, use a high-quality coal-tar based sealer. After the asphalt driveway has initially hardened and cured you should continue to seal the driveway every three to five years.
Asphalt is actually very flexible when it is first poured due to the lightweight oils that it contains. These lightweight oils evaporate over time, making the asphalt harder. Sealing a driveway before it is time will prevent this evaporation, leaving your driveway soft and malleable.
