Best asphalt driveway pros near Sun Prairie, WI

An ideal driveway gradient is between 2% and 5%. Anything lower than 1% or higher than 15% can cause problems for your car or property. A driveway with less than a 1% slope increases your likelihood of flooding and water damage, while a driveway with a 15% grade or higher can be too steep for safe traveling.

There’s no single best asphalt grade—it all comes down to where and how it’s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional’s input is always a smart move before making a decision.

When hiring an asphalt paving contractor to install your driveway, ask as many questions up front as possible. Here are a few questions to ask a prospective driveway contractor:

• How many years of experience do you have?

• Are you licensed, bonded, and insured?

• Do you have worker’s compensation?

• Do you use subcontractors on your projects?

• Do you clean up after the job is done?

• Who is responsible for any damage to lawn or landscaping?

• Do you provide a guarantee or warranty on your work?

• Do you give free estimates?

• What is the timeline for completion?

• How do you handle change orders?

• Can you provide at least three references?

• Can I see some of the work you’ve done?

Chip seal layers gravel and a liquid bitumen one at a time on-site, while asphalt directly pours a pre-combined mixture. Asphalt must be sealed, but it will last up to four times as long as chip seal driveways. Aesthetically, chip seal has a natural, rustic look compared to the traditional asphalt slab.
