Get matched with top asphalt driveway pros in Dumont, IA

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 overlay or top coat costs between $3 and $7 per square foot. For a standard, single-car driveway that’s 10 feet wide and 20 feet long, that’s a total of between $600 and $1,400. For a two-car driveway, you’re looking at a total of between $1,200 and $3,000.

The decision to repair or replace your driveway depends on the extent of the damage. If your driveway has a few small cracks, a simple repair will do the trick. If you see larger cracks and potholes, it may be time to consider resurfacing or replacement. Resurfacing is a great option if more than 25% of the surface is damaged, but if the damage is extensive—deep cracks or significant sinking—it’s best to replace the driveway entirely. A new driveway, with proper care, can last decades while patching or resurfacing might only hold up for a few years before needing more attention.

Like all driveway materials, asphalt can crack in the wrong conditions and with age. Many things can cause asphalt to crack, including shifting soil or settling under the foundation. Other common causes are driving oversized vehicles on the asphalt, tree roots, and using rock salt during the snowy season. Proper installation and sealing the driveway every 10 years can help prevent cracks.
