If you have a crack on your asphalt driveway that looks similar to the scales on a reptile's back, that is known as alligator cracking or crocodile cracking. It is a type of fatigue cracking that usually happens due to deterioration of the asphalt over an extended period of time. Here are some tips for repairing the cracks so you don't have to replace the entire driveway.
Prevent Further Cracking
If you see even the tiniest crack in your asphalt, act fast. This is the best way to prevent further cracking. Advise everyone in your home to stay off the asphalt driveway and park on the street instead. Put up signs if needed to keep traffic off the asphalt. The weight of the vehicles can cause the cracks to get worse.
When you see a small crack in the asphalt, apply crack filler immediately. Another option is to use sealcoating on that area of the driveway. This will keep the crack from deepening or spreading along the driveway. It also makes your patching and repair work much easier.
Gather the Supplies
When you are ready to repair the alligator crack, make sure you have gathered the right supplies. For this type of repair, you will need a patching material. Some hardware stores carry an asphalt patching material made specifically for alligator cracks, which is the best patch you can get. Aside from the filler material, you will also need a squeegee, pressure washer or garden hose, and a scrubbing brush.
Patch the Alligator Crack
Now that you have your supplies, you can start preparing the driveway. Before repairing a crack, you should make sure the area is clean. If the crack is large enough to fit your fingers into, you can check for debris and pull it out. There might be leaves or branches from nearby trees lodged in the cracks. Also take a scrub brush and some mild soap and clean the area, then rinse it thoroughly with a garden hose or pressure washer. Once it dries, you can start repairing it.
Read the directions on the patching material to see if any mixing is needed before application. Pour a small amount of the alligator patching material in the middle of the cracked area. Use the squeegee to spread out the patching material around the alligator cracks. If you need more patching material, pour more of it, then squeegee it once again. You want to have even coats of the patching material across the cracked area. Once smooth, let it dry for several hours. To learn more, visit Armour Pavement Inc.
