Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

The size of your driveway apron will vary based on your town's building codes. On average, they range between 12 and 24 feet wide and eight to 15 feet long. One end of the apron usually matches the width of the driveway—10 to 12 feet wide for a single-car driveway—while the street end flares out to allow cars to turn in and out.

Driveways last 25 to 50 years, but you’ll notice cracks and possible missing pieces during this time. Regular maintenance, such as filling cracks, reapplying sealer, and ensuring that water does not erode the base material, can help extend the lifespan of your driveway. Gravel driveways should be regraded to fill in uneven areas every year or two, depending on how frequently it is needed.

Sometimes, when people talk about asphalt driveways, they’re actually referring to asphalt concrete, which is a completely different compound. Asphalt concrete is asphaltic cement combined with sand or grit. It is significantly more lasting and durable than regular asphalt but also much more expensive. If you’re considering using asphalt concrete, ask an asphalt company for their expert opinions.
