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.

The average cost to repair an asphalt driveway is around $2,459 to $2,500. However, prices can range from $100 for minor DIY crack filling to over $4,000 for more extensive professional work. Costs are often calculated per foot, with minor repairs costing $1 to $3 per linear foot and heavier damage like potholes, sinking, or crumbling costing $2 to $5 per linear foot. Patching smaller potholes can cost around $2 to $3 per square foot. The final price depends on the severity and extent of the damage, driveway design, local contractor rates, and whether sealing is included. For major repairs, it is recommended to hire a professional, and you may get a better deal by bundling repair and sealing services together.

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

When comparing installation costs, asphalt is often less expensive upfront than concrete. Asphalt prices typically range from $7 to $15 per square foot, while concrete can range from $3 to $18 per square foot. However, long-term costs should also be considered. Concrete driveways generally last longer (up to twice as long) and require less maintenance, which can make them more affordable over their lifespan. While asphalt has a lower installation cost and is easier to repair, it requires more frequent maintenance, such as sealing, which can add up over time. Therefore, while concrete is more expensive initially, its durability may offset the cost in the long run.
