Get matched with top asphalt driveway pros in Kooskia, ID

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 should be sloped with a minimum 2% slope—anything lower will cause precipitation and runoff to collect. A 2% slope is the equivalent of a 2-foot rise over 100 feet. One quick way to check the integrity of your driveway’s slope: no more than four inches of water should collect on the surface longer than 15 minutes after rain.

Asphalt edging secures the sides of your driveway to prevent crumbling and cracking over time. Most driveways have edges with a 45-degree grading. This helps transfer some of the stress from the asphalt to the ground underneath. If your driveway doesn’t have proper edging, the pressure from your car may break down the edges over time.

There are quite a few differences between concrete and asphalt. Concrete is more costly up front and more challenging to repair. Asphalt does better in cold climates and works well with radiant heat systems. Porous asphalt is also excellent for wet climates, as it allows the water to drain away. However, it does get unpleasantly hot in the summer and requires more maintenance than concrete.
