Best asphalt driveway pros near Unionville, MO

Asphalt is made of aggregate materials (sand, rocks, and gravel) and bitumen, a viscous, petroleum-based, waterproof substance. These materials are mixed together at extremely high temperatures to form asphalt.

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

In most cases, you don’t need a permit to repave your driveway, although some exceptions exist. If you’re widening your driveway and plan on widening the apron as well, you’ll usually need a permit from the Department of Transportation in your area. This permit costs between $50 and $300 in most cases. Most municipalities will also require a certified and insured contractor do the work relating to the apron and curb cut. You can contact your building department or ask your paving company if you need a permit. Your driveway professional will usually pull the permit for you.

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.
