Driveway Sealcoating FAQs, answered by experts

The best ways to increase the lifespan of your driveway are to carry out proper maintenance and get repairs done quickly. First, reseal your driveway every one to three years to protect it from the elements. If you start to notice significant cracks, hire a professional to diagnose the problem before it gets more serious. You can also use sand instead of salt when de-icing your driveway (since salt is corrosive) and clean your driveway annually using a pressure washer to keep it in tip-top shape.

Asphalt is made of aggregate materials (sand, rocks, and gravel) and bitumen, a viscous, petroleum-based, waterproof substance. These materials are mixed together at extremely high temperatures to form asphalt.

The costs range from $0.15 to $0.50 per square foot, depending on the asphalt condition, sealant type, and labor.

DIY asphalt repair is feasible for small issues like cracks or potholes, provided you have the correct materials and tools. However, for more extensive damage or to ensure a durable, smooth surface and prevent further deterioration, engaging professional services is recommended for their expertise and long-lasting results.

Instead of a set number of types, asphalt comes in variations designed for different needs. Some are categorized by temperature—hot mix, warm mix, and cold mix. Others are sorted by composition, like dense-graded, gap-graded (such as Stone Matrix Asphalt), porous, and mastic asphalt. There are also modified versions with added compounds like polymers, rubber, or emulsions. Instead of focusing on a number, it may be more useful to understand how contractors customize asphalt for durability, climate, and traffic conditions.
