How To Patch An Asphalt Crack

Construction & Contractors Blog

When it comes to driveways, asphalt is one of the most durable and long-lasting paving materials around. Yet even properly installed asphalt is bound to develop cracks as time goes on. Luckily, such cracks are easy to fix on your own--provided you act while they're still small. If you have an asphalt driveway at your home, read on. This article will provide an overview of the crack patching process. 

Step 1. Preparing the crack.

The secret to a long-lasting patch is properly cleaning the crack first. Make sure to remove any loose sand or dirt using a broom. You may need to use a screw driver or some other tool to help work larger debris loose. Then use a hose to wash away any residual dirt and dust. Allow the crack to dry completely before proceeding. 

Step 2. Gathering materials.

It doesn't take much to successfully patch an asphalt crack. Here's what you'll need:

  • tube of asphalt repair compound
  • caulk gun
  • small stick from your yard
  • a handful of loose gravel from the side of the driveway
  • a handful of loose sand, also collected from the side of the driveway

Those last few items might strike you as a little odd, but don't worry! They will play a key role in ensuring an aesthetically pleasing final product.

Step 3. Applying the patch.

If the crack you will be patching is more than two inches deep, you might opt to fill it partway with some of the loose gravel you collected from the side of the driveway. This is a nice way to reduce the amount of repair compound you have to use. The gravel will also help to strengthen the patch.

Use your caulk gun to apply a bead of repair compound just to the height of the crack. Take care not to overfill it. Then, use your small stick to spread the compound onto the asphalt on either side of the crack. This will increase the amount of contact between compound and asphalt, leading to a stronger bond.

Step 4. Final touches.

Now, if you stop at the end of Step 3, your patch will turn out just fine. However, it will also stand out sharply from the rest of your driveway. If you want, however, there are a couple of more things you can do to help your crack blend in with the rest of the asphalt surface.

First, take some more of the pieces of gravel you collected in Step 2 and gently press them into the surface of the repair compound. Of course, you'll only want to do this in places where the crack is wide enough to permit it.

Be sure the rocks are pressed down to the same level as the rest of the asphalt, and that the sealant is covering their edges. This will ensure they don't work free over time. Finally, sprinkle your handful of sand over the fresh repair compound. Voila, your crack is now fully patched and camouflaged! If your crack is too expansive to fix on your own, contact a company like Bonness Inc for assistance.
