Asphalt driveways are cheap to install and fairly long lasting, but they are not indestructible. A long, hard winter with plenty of snow, ice and rain may cause cracks or potholes. Water that gets into cracks in the driveway may freeze under the surface, causing the driveway to rise during the winter then sink once the ice thaws in the spring. Applying a strong patch that seals up cracks may prevent this from happening again.
Things You'll Need
- Cold chisel
- Stiff brush
- Cold asphalt patch
Place a chisel at the bottom of the crack and strike the top of the chisel with a hammer to make the bottom of the crack as wide as the top. It should be even all the way to the bottom. This creates a channel for the patch to flow into evenly.
Sweep out the loose pieces using a stiff brush and a vacuum cleaner.
Mix up your cold patch by stirring it, or preparing it according to the instructions on the label.
Place gravel down at the bottom of the hole or crack if the crack is deeper than 2 inches. The patch depth should be no greater than 2 inches at any one point once the asphalt patch is poured, to keep it from being weak.
Pour the cold patch into the crack or hole and press down on it using a tamper to make sure it gets into any small holes. Allow the patch to dry for the amount of time specified on the packaging.
Tips & Warnings
- If you do not have a tamper, drive over the new patch with your car.
