Driveway Sealcoating questions, answered by experts

Instead of a set number of types, asphalt comes in variations designed for different needs. Some are categorized by temperature—hot mix, warm mix, and cold mix. Others are sorted by composition, like dense-graded, gap-graded (such as Stone Matrix Asphalt), porous, and mastic asphalt. There are also modified versions with added compounds like polymers, rubber, or emulsions. Instead of focusing on a number, it may be more useful to understand how contractors customize asphalt for durability, climate, and traffic conditions.

Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

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?

Asphalt dries and cures best between 50 and 85 degrees Fahrenheit. This range allows moisture to evaporate quickly without causing the asphalt to cool too fast, which can negatively affect the drying process. However, keep in mind that other weather conditions can also affect curing and drying times, such as precipitation and humidity.

Sealcoating is worth the investment because it protects your driveway from damage, extending its life and the timeframe in which you need to replace it. Sealcoating costs around $500 on average, while replacing a driveway costs about $5,000. Sealcoating delays the need for replacement and it also helps keep your driveway looking newer for longer. As an added bonus, sealcoating can boost your property value and curb appeal, making it worth the sealing cost once every five years.
