Asphalt is among the most popular materials used in driveways. While proper installation guarantees longevity, the surface is still susceptible to damage. So, when you notice cracks on your pavement, you should make timely repairs. But what are the key things that may lead to asphalt cracking? Learn about the common causes of such damage in this guide.
Damage from Excessive Moisture
Asphalt has excellent water-resistive properties, but this doesn't exclude it from moisture damage. After many years of exposure to moisture, your driveway's gravel base will start to wash away, resulting in a shift in the surface layer. Eventually, you'll notice crack formation. If you don't seek the services of a paving contractor immediately, water will seep into the cracks, causing extensive damage. Besides applying a sealant to the cracks, your paving contractor will recommend an adequate drainage system to divert water from the driveway.
Extreme Heat from the Sun
The sun's heat can break down the asphalt paving aggregate material during the hot season. This causes moisture in the driveway to dry up, making the surface weak. A weak pavement is susceptible to cracks from foot and vehicle traffic. So on the first sign of sun-related asphalt damage, speak to a local paving contractor. They will recommend appropriate repairs to avoid extensive driveway deterioration.
A Shift in the Ground
You may experience cracks in the asphalt driveway from earth shifts occurring under the asphalt. This scenario could happen following an earthquake or after a major storm. Remember that when there's a shift in the ground, the materials used at the base of the pavement will move. This movement creates a lot of pressure that causes the asphalt to crack. While you can't stop natural events, regular driveway maintenance will ensure that the pavement stands up against ground movement.
A Poorly Installed Driveway
When installing your asphalt driveway, you should hire the services of a reputable paving contractor. While an inexperienced professional might be less costly, they may not properly install the base. Besides, they may use light materials to save on cost and time. Keep in mind that when poor-quality materials are exposed to changing weather conditions, they'll expand and contract, causing cracks on your asphalt pavement.
You should call an asphalt paving contractor for repairs when you notice cracks on your asphalt driveway. Waiting too long could lead to extensive damage that might require you to replace the driveway.
