Question 1

How can I increase the lifespan of my driveway?

Accepted Answer

•

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.

Question 2

Can you pave over an existing driveway?

Accepted Answer

•

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

There’s no single best asphalt grade—it all comes down to where and how it’s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways.

Question 4

Is it OK to Pour Concrete Over Asphalt?

Accepted Answer

•

You can pour concrete over asphalt if it’s in good condition, thick, stable, and well-compacted. Concrete is more durable than asphalt and can extend the lifetime of your driveway without having to pay frequent asphalt driveway repair costs or replace it completely.

But this is best reserved as a temporary solution based on budget restraints, as asphalt requires more frequent repairs and assessments than concrete. Once that concrete top is poured, it’ll be harder to accurately understand what’s happening beneath that layer, which could lead to more issues.

Question 5

What is the lifespan of asphalt pavement?

Accepted Answer

•

You can expect your asphalt pavement to last anywhere from 20 to 30 years, or 25 years on average. The life expectancy of your asphalt driveway depends on the climate, the amount of traffic, and how well you maintain it. While you can’t necessarily control some of these factors, you can control the amount of maintenance effort you put into your driveway.

To prevent your asphalt from deteriorating prematurely, you should follow a good maintenance routine involving regular cleaning, reparation work, and resealing.
