Reasons Why Your Asphalt Driveway Is Crumbling

With summer on the way, you might notice that your asphalt driveway is crumbling in Washington. Temperature changes, along with the wet conditions Washington is famous for, can contribute to wear and tear on your asphalt driveway and cause it to crumble.

When your asphalt driveway shows signs of damage, like cracks, potholes and crumbling, make sure you get it repaired right away. The longer you put off repair, the more likely the damage will increase and you’ll need a complete driveway replacement. In fact, if your asphalt is crumbling, it may already be too late.

Here are the main reasons your driveway will start to crumble, and what you can do to mitigate damage:

  • Temperature and weather changes: Asphalt is subject to the effects of nature, especially in a high precipitation area like Washington. Water can permeate the asphalt, then freeze and cause cracks. It also weakens the asphalt so it’s more susceptible to wear and tear from other sources. Heat can also soften and weaken the asphalt’s surface. If your area has undergone extreme temperature changes recently, watch your asphalt carefully for signs of cracks, potholes and crumbling.
  • Improperly sealed asphalt: Sealing an asphalt driveway can help protect the surface from wear and tear, but only if it’s applied at the right time. Asphalt needs to cure before you can sealcoat it—in fact, you may need to wait up to a year before it’s hard enough to seal. Otherwise, you risk ruining the material’s flexibility. Make sure that if you’re installing a new asphalt driveway, you follow the paving contractor’s instructions about how long to wait before sealing the asphalt, or risk a crumbling asphalt driveway in Washington long before its lifespan should be over.
  • Insufficient sub base: The sub base is used to add strength and longevity to your driveway, when it’s installed properly. Paving contractors use heavy stones and geotextile products to create a strong, sturdy base that should extend past the edges of the asphalt. However, if the base isn’t properly created or doesn’t extend past the end of the driveway, the edges will start crumbling. It may also cause the base to shift or sink when the ground is wet.
  • Loose sand or gravel: Asphalt is tough and strong, but still susceptible to wear and tear from loose sand and gravel, especially if the sub base is insufficient. The more you drag rocks and sand over the surface of your driveway, the more likely you are to see cracks and gouges, which can become bigger over time.
  • Excessive wear and tear: Finally, if you don’t treat your driveway well—that is, if you park heavy equipment on it, turn your wheels back and forth repeatedly or let lawn chairs and trailer hitches create dents—you’re more likely to see cracks and crumbling over time.
