Seal Asphalt Driveway
Tim Carter received the following email from Russ not too long ago:
"I read your column in the Chicago Tribune. On Aug. 18, 2016, you wrote that "Sealing a blacktop driveway is unnecessary." I saved the article because I had a new asphalt driveway installed that summer. On Jan. 9, 2020, you wrote, "Be careful when asphalt sealing driveway." You made no mention of not needing to seal in the later article. So what is the prevailing mindset? Forget aesthetics. What is best for the 'health' and long life of my still unsealed driveway? There are no cracks in it. Thank you."
This is a very common question.
The answer is not straightforward about sealing asphalt and you'll discover LOTS of conflicting information on the Internet about this topic. LISTEN to the above podcast to discover what you need to know.
As always, engage your critical-thinking gray cells and look all around you for data to help you decide what is the best thing to do.
For example, do you see public roads get sealed? No.
You may see some states do it using tar and chip. Some regions call it seal coating. Here's a photo of it being done in Ohio:
