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.

While paving a driveway is possible to do as a DIY project, we don’t recommend it. Hiring a driveway professional to pave it will ensure that your driveway looks neat and clean and lasts for years to come, and it will also prevent a weak driveway and, potentially, damage to your foundation. Paving a driveway requires heavy machinery, and while you can rent the equipment needed, operating it close to your garage slab or around your home’s foundation can crack it and lead to structural issues. 

Several materials are suitable for steep driveways. Gravel and crushed stone are affordable options that provide good traction. Permeable pavers—such as plastic, rubber, or concrete—filled with gravel or crushed stones are also excellent, as they allow water to drain without causing erosion and perform well in ice and snow. Another option is resin, which can be coated with an anti-slip finish and helps prevent puddles. For added stability, you can install a retaining wall to prevent pavers and gravel from shifting over time.

New asphalt goes through two stages: drying and curing. Drying typically takes 24 to 72 hours, after which the surface is solid enough for light use like walking or careful driving. While you may be able to park on it after 72 hours, the surface is still soft and should be treated gently. Full curing is a much longer process, taking anywhere from 30 days to a full year for the asphalt to reach maximum strength. During this extended curing period, the asphalt is susceptible to damage from heavy vehicles, sharp objects, and high temperatures. Factors like weather, the specific asphalt mix, and application thickness all influence drying and curing times. For the most accurate timeline and to ensure the longevity of your new asphalt, it is always best to consult with your installation contractor for their specific recommendations.
