If you have invested in an asphalt driveway or parking lot, then be sure you take steps to preserve its longevity. Regular maintenance, like asphalt seal coating, not only makes your driveway or parking lot look better but also last longer. Some asphalt surfaces need resealing more than others, depending on usage and location. Here are some signs it's time to reseal your asphalt or whether you may need more extensive repairs.
New asphalt is a nice, even dark color, not a dull gray. Over time, the sun and other weather elements can cause the color to fade. While this may only seem to be an appearance issue, faded asphalt means it has lost much of its protection. If your asphalt is very light in color and it's been several years since your asphalt was sealed, then now is the time to do it. The sooner you reseal your surface, the less likely your asphalt will suffer damage.
Cracks and Chips
When your asphalt driveway or parking lot is unsealed or the seal is worn, you will start to see more cracks and chips. These may lead to potholes forming. You can repair minor potholes and fill cracks with minimal extra work before resealing. However, major potholes or multiple potholes may require major resurfacing. Keeping up with asphalt maintenance keeps these small issues from destroying your pavement.
Sealing keeps water from entering cracks and causing damage to your asphalt surface. Without sealing, water contributes to surface damage that causes water pooling. Water can also damage the seal itself, which is the reason why you need regular resealing. Rainy and snowy areas are especially vulnerable to water damage. During cold weather, water will leak through cracks and freeze. The frozen water expands to make cracks and chips bigger.
Sealing your asphalt protects your asphalt surface from potentially damaging chemical stains. Certain types of oils and solvents can break down the asphalt's binders. Taking care of stains as soon as you see them and keeping your pavement sealed are the best ways to reduce damage. However, if you wait too long and the oil has penetrated the top layer, then your asphalt needs deeper repair.
Don't delay in resealing your asphalt. If you wait too long, then simple sealing and minor repairs will turn into a major project. Your asphalt driveway or parking lot could need complete resurfacing or even replacement. If you have questions about when to reseal your asphalt and how often to do it, contact an asphalt sealing company.
