The Benefits of Seal Coat Your Driveway in New Hampshire Weather!

Share


The primary reason to sealcoat an asphalt pavement is to protect the pavement from the deteriorating effects of sun and water and snow in the New Hampshire marketplace. When an asphalt pavement is exposed to sun, snow, wind and water, the asphalt hardens, or oxidizes.

New Hampshire weather causes the pavement to become more brittle. As a result, the pavement will crack because it is unable to bend and flex when exposed to traffic and temperature changes. A sealcoat combats this situation by providing a waterproof membrane which not only slows down the oxidation process but also helps the pavement to shed water, preventing it from entering the base material.

A secondary benefit of seal coating is an increase in the surface friction it provides. This is accomplished by the additional texture the cover aggregate adds to the pavement. With time, traffic begins to wear the fine material from an asphalt pavement surface. This result in a condition referred to as raveling.

When enough of the fine material is worn off the pavement surface from New Hampshire snow or weather, traffic is driving mostly on the course aggregate. As these aggregate particles begin to become smooth and polished, the roadway may become slippery, making it difficult to stop quickly.

A sealcoat increases the pavement texture and increases the surface friction properties. To Learn more about seal coat your driveway call Sam Schwanke directly 603-721-2438

  1. I didn't know that your driveway could become more slick from weather, and could become dangerous. I have been thinking about how to take care of my driveway; and I've never tried seal coating before. I can see how it would be good to have done, so I don't need to worry about my car slipping off of my driveway. http://www.wekickasphalt.com/sealcoating/
