Chip seal layers gravel and a liquid bitumen one at a time on-site, while asphalt directly pours a pre-combined mixture. Asphalt must be sealed, but it will last up to four times as long as chip seal driveways. Aesthetically, chip seal has a natural, rustic look compared to the traditional asphalt slab.

Asphalt is not a type of concrete. While both are a common type of pavement, asphalt is composed of aggregates (like sand and gravel) and bitumen; concrete is a mixture of cement, aggregates, and water. Here are some of the key differences between asphalt and concrete driveways.

Driveway aprons typically range between four and seven inches thick, though your town's building codes will likely have specific requirements. Additionally, you may need to add a layer of permeable aggregate in the excavation below your paved apron to ensure proper stormwater drainage.

Even with regular maintenance, most driveways don’t last much longer than 30 years. Alligator cracking is a clear warning sign that your driveway’s foundation is failing, and cracks that are deep and wide can let water in, causing more damage. Standing water is another red flag. If your driveway doesn’t drain properly, it’s going to degrade slowly. Finally, if you’re seeing dips or uneven patches, that’s a sign the base layer or soil is shifting. If these issues pop up, it’s time to replace your driveway.
