Get matched with top asphalt driveway pros in Alton, MO

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.

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.

An asphalt driveway should be at least 3 inches thick over a compacted gravel base. Areas with poor drainage should have a thicker stone base. To install a new asphalt driveway over an existing driveway, the new asphalt should be at least 2 inches thick and the existing driveway should be in relatively good condition.

Wet cutting is usually the preferred method. It controls dust, which helps protect your lungs and makes for a cleaner working environment. Plus, the water cools the blade, preventing overheating and prolonging its life while providing smoother, more precise cuts. The downside is the mess—water and asphalt sludge can be messy to clean. Dry cutting, though convenient if water isn’t available, creates a lot of dust, which can be harmful. This also increases the risk of blade damage due to overheating. So, if you have the option, wet cutting is the better method for most asphalt jobs.
