Protecting Your Asphalt from Spring Rain

Asphalt Driveway Protection

You’ve heard the saying “In like a lion, out like a lamb”, but as winter ends and spring begins, are the effects of winter weather on your asphalt driveway or parking lot as mild as the temperatures that have sprung.  If your pavement has escaped unscathed this past winter, April showers shouldn’t cause too much havoc on your asphalt pavement.  However, if you did not properly maintain your asphalt driveway or parking lot over the winter months and the Pittsburgh weather got the best of your paved surface, then you may be in store for potential damage in the spring.

To better understand the vulnerability of your asphalt this spring, RoadStar Paving, trusted asphalt pavers in the Pittsburgh area, breaks down the situation below.

Problem:  Water Causes Asphalt to Deteriorate

Water, whether it be pooling on top of the asphalt, continuously hitting the pavement or seeping into cracks and being trapped in the soil underneath the pavement, will slowly begin to deteriorate asphalt.  In the springtime when temperatures are fluctuating, this creates a freeze/thaw cycle.  The constant contraction and expansion of water molecules cause stripping, which is the debonding process between the asphalt binder and the aggregate.  As a result, the pavement becomes weak and susceptible to further damage.

Solutions:  Sealcoating, Proper Drainage, and Regular Maintenance

Just because April showers will soon be appearing, it does not mean that damage to your asphalt has to as well.  There are ways to protect your asphalt from spring rains.

  • Sealcoating – One of the first ways to protect your asphalt investment is with seal coating.  Sealcoating your Pittsburgh driveway or parking lot prevents water from seeping into cracks and causing all sorts of problems.  It also protects your asphalt from UV rays and vehicle fluids.  RoadStar Paving recommends that you apply a high-quality sealant every three years to protect and extend the life of your asphalt pavement.
  • Proper Drainage – If you have noticed that water is pooling in certain areas on your asphalt surface, then you probably do not have proper drainage.  Steps for proper drainage should be determined at the time of installation, but if it wasn’t or if it was done incorrectly, you must address it immediately before it presents a problem.  Some asphalt pavers in Pittsburgh may use porous asphalt, which allows water to filter through the asphalt layers and move to waterways.  Often, parking lots are sloped to allow for proper drainage.
  • Regular Maintenance – If you spot even the smallest crack, it is important to repair and seal it immediately. You want to avoid allowing water to infiltrate your asphalt pavement.  Waiting too long can result in larger, more costly repairs down the road. Regular maintenance is an easy and cost-effective way to prevent unsafe conditions, expensive repairs and loss of curb appeal.
