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.

It takes recycled asphalt 48 hours to initially harden and up to 3 months to fully cure. It’s best to stay off of recycled asphalt for at least 48 hours, then you can walk or drive standard vehicles on it. Hold off on driving heavy trucks or equipment on it for at least 7 days. Allowing the surface to melt together and harden ensures that the surface stays durable and long-lasting. 

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.

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.
