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.

The most obvious disadvantage of permeable paving is that the cost is typically higher compared to non-permeable concrete, pavers, or asphalt methods. Also, the porous material can get clogged with dirt and debris, requiring cleaning and power washing more frequently than standard paving materials and methods. Although permeable paving is not ideal for highways, airports, and other surfaces supporting heavy traffic and machinery, it is suitable for regular residential driveways.

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.

In most cases, driveway repair is worth the investment. Your driveway is one of the first things people see when they look at your home, so repairing cracks, chips, and potholes can improve your home’s curb appeal and overall value. Repairing your driveway is also almost always more affordable than replacing it entirely—an average of $1,765 compared to the cost of replacing a driveway, which typically costs around $5,000.
