Asphalt is commonly used for driveway paving projects because of its strength, durability, and resilience. However, it is not immune to damage. Over time, structural imperfections occur that affect its integrity. Being mindful of these issues makes it easier to identify problems before they grow worse. Here are some of the most common causes of damage to asphalt driveways.
What Causes Asphalt Driveway Damage?
1. Moisture Intrusion
It’s impossible to avoid moisture exposure, and the asphalt's condition determines how well it will respond to water. The material often develops cracks and small openings over time, creating space for moisture to seep in and erode the sub-base. Once the foundation is compromised, the pavement itself eventually loses its support and begins to crumble. While you can’t prevent rain, you can improve your landscape’s drainage by installing a trench drain to channel water underground and away from the surface.
2. Heavy Weight
The risk of asphalt developing premature imperfections increases whenever the surface is exposed to heavy weights. Hefty lawn equipment and trucks can subject the asphalt to unexpected pressure and strain. The ground naturally weakens in response, leaving it more vulnerable to cracking and breaking down. If you need to park on your driveway, move the vehicle from one spot to another so the asphalt wears down evenly. Try to avoid parking more than one vehicle on the surface, too.
3. Root Damage
If trees flank the location of your driveway paving project, it’s possible for their roots to grow far enough to interfere with the asphalt. Roots are quite strong; as they push upward, they can cause the driveway’s foundation to move. This leaves the asphalt vulnerable to cracks and breakage. Remove any trees situated too close to the driveway and avoid planting new ones to reduce the risk of root penetration. Applying a root barrier may also be helpful if you want to stymie growth in specific areas.
