Would you like to double the longevity of your driveway? If so, you’re going to want to regularly sealcoat your asphalt. As your local contractor for asphalt paving and sealcoating in Middlesex County, MA, we’ve found that the average life of an asphalt driveway is about 15 years, but regular sealcoating can increase the life of a driveway to 30 years or even more!

Asphalt pavement is made up of stone, sand or aggregate and asphalt cement. The asphalt cement is the glue that holds everything together. Over time, sun, rain and snow cause the oxidization of the asphalt cement and the driveway will become brittle and less resistant to the weight placed on it every day. In addition, substances that contain petroleum derivatives, such as oil, transmission fluid and gasoline, can actually dissolve the asphalt, causing it to weaken over time. Sealcoat functions to protect the asphalt in your driveway from the elements and other damaging factors.

So the question isn’t if you should sealcoat your driveway, but rather how often. Knowing when to sealcoat your driveway is actually easy to determine, if you know what to look for. Below are a few examples to help you determine if it’s time to sealcoat your driveway:

  • Your driveway is new: If you recently had your driveway installed, it will need some time to cure. But once the asphalt has cured, you’ll want to sealcoat it before it can be affected by the elements or other damaging factors. Typically, a new driveway should be sealcoated about 3 to 6 months after installation.
  • It’s been a few years since your driveway was last sealcoated: Even if your driveway shows no visible signs of damage or fading, you should still sealcoat it about every 2 to 3 years. If it’s been a few years since your last sealcoating, it’s time for a fresh application.
  • Your driveway appears to be fading: Fresh asphalt is dark black, but due to oxidization, it will start to fade over time. If your driveway looks faded, or more gray than black, then it’s probably time to have it resealed.
  • You’re noticing frequent cracks in your pavement: Oxidization and products that contain petroleum derivatives can cause the asphalt in your driveway to become brittle and crack. If you notice that your driveway is cracking, it may be time to have the asphalt resealed.
  • You’ve experienced severe weather conditions in the past year: If your area has experienced heavier rain or snowfall in the past year, frequent freezes and thaws or a summer with unusually high temperatures, the asphalt in your driveway may break down more quickly than normal. Under these severe weather conditions, you may need to sealcoat your driveway every year.

Paying attention to the condition of your driveway and regularly sealcoating your asphalt when needed can significantly increase the life of your driveway.
