The dimensions of a driveway apron vary based on local building codes, the width of your driveway, and the distance between the driveway and the road. On average, aprons range from 12 to 24 feet wide and 8 to 18 feet long. Typically, the end of the apron connected to the driveway matches its width—such as 10 to 12 feet for a single-car driveway—while the end at the street flares out to allow cars to turn in and out more easily. In some areas, you may not be responsible for the portion of the apron that extends beyond the sidewalk, but this depends on local laws.

The stones do not work well on uneven ground. If the stones are not buried into the ground and made level upon installation, they almost certainly will shift or crack on uneven ground. Additionally, rainwater or water from sprinklers can run under the edge of an uneven paver, causing erosion. In a freeze and thaw cycle, trapped water under the paver can cause the problem to worsen by shifting the stepping stones around. Use a bubble level to make sure the ground under each paver is as even as possible, even if the nearby ground is uneven.

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.

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.
