Interlocking pavers offer a number of advantages over regular pavers. For instance, they’re more durable, more resistant to shifting, and easier to repair. There are also permeable options that allow for drainage. However, interlocking pavers are more often more expensive than regular pavers and are prone to growing weeds over time.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

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. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional’s input is always a smart move before making a decision.
