How To Repair Asphalt Cracks

Posted on: 29 March 2016

Cracks in your asphalt are to be expected. They most commonly occur when the soil beneath the slab is shifting do to a growing tree root. They can also pop up if there is constantly too much weight in a weak spot of the asphalt. Luckily, making simple patches to asphalt is easy, if you use the right products. This article explains the best tools and methods to use if you are trying to fill a small asphalt crack. This will slightly reinforce the asphalt, but mainly service as a cosmetic repair.

Clean the Crack

Before you being any work on the crack, you need to thoroughly clean it out. You can sweep out the crack, or even use a shop vacuum to suck out dirt and loose asphalt. Then, use your hose or a pressure washer to clean the asphalt around the cracks. This lifts any grime within the asphalt pores that could reduce the strength of the adhesive of the new patch.

Using Asphalt Patch

At most home improvement stores you will be able to find asphalt mixture and asphalt patch. These two products are very different. Asphalt mixture is not good for patching cracks. While it is likely very similar to the existing asphalt, it is not meant to be poured in small portions. It will not stick into the crack and likely break away after while. Asphalt patch works way better because it has adhesive mixed in with the formula. This means it will bond to the existing asphalt and last much longer. Asphalt patch is slightly more rubbery than normal asphalt, even when it is completely dry. Of course, it gets more rubbery when the temperature increases. But this is a good thing because it means that it will expand and contract when the asphalt shifts and not just break away.

Applying Asphalt Patch

Applying the asphalt patch is simple if you have a squeegee broom. This is basically a squeegee on the end of a full size broom handle. This allows you to spread the crack filler without hardly bending over. Since asphalt crack is premixed you just pour it directly into the crack. Then, use the squeegee to level it out. Try to taper the edges so they blend in with the existing asphalt. You want to make sure that there are no ridges or areas where the patch can pull up or cause a trip hazard.
