4 Steps To Driveway Crack Repair

Cracks in an asphalt driveway are not just cosmetic blunders, they are also signs of a failing asphalt structure. The best thing that you can do as the owner of an asphalt driveway is to fix your cracks as soon as they appear. Follow the steps below to see how Yellowstone Pavement Solutions goes about addressing the issue of asphalt cracks.

Step 1: Locate all Cracks Over 1/4″ in Width

The first step in professional asphalt crack repair is to identify all cracks that need to be sealed. Cracks under 1/4″ will be sealed with a sealcoat emulsion. If the driveway is not being sealcoated then all cracks need to be filled. 
 

Cracks may also have to be categorized to determine if they are a static or working cracks. Working cracks should be routed and filled. Routing a working crack will give a greater rubber reservoir and therefore more movement of the crack is possible without splitting the rubber.

Step 2: Thoroughly Clean Cracks with Grazor

Once all cracks are located and the crack type is detmermined, YPS takes the extra step of grazing the cracks. This wheeled brush thoroughly cleans out all debris and organics from the existing asphalt cracks. This extra measure will ensure that the hot rubberized asphalt material fully bonds to the sides of the crack.

Common issues that arise from uncleaned cracks are pull-ups and bubbling. Pull-ups (or pull-outs) are an indication of dirt still remaining on the walls of the cracks. This issue is easily addressed by a blowing the crack out with compressed air following the grazor. Bubbling is usually an indication of water remaining in the cracks or organics that were not removed. Again, this issue is avoided by proper cleaning.

Step 3: Fill Cracks with Rubberized Asphalt Material

Cracks are filled with a rubberized asphalt material at approximately 400 degrees Fahrenheit. Cracks are filled with either and oil jacketed melter, or a direct fire melter. Once material is heated to the proper application temperature, the cracks are filled from the bottom up.

We usually band our cracks roughly 1″ on either side of the crack to create a water tight seal. The main effort in crack repair is to stop the intrusion of water, so we take every necesseary precaution to avoid this.

Step 4: Refill if Necessary. Ensure Proper Banding

Cracks can commonly extend down to the sub base of a pavement surface. This means that many cracks are 3-4 inches deep and require additional material. By reviewing all of our repairs after they have set, YPS is able to guarantee a professional fix.

  1. I unfortuately will have to try these techniques on my concrete driveway that is not even two years old. I don’t know if it would be worth it, but I’ll give it a try. Thanks for the info as I am trying to figure out the best way to take care of the cracks.

    1. That sounds like a tough situation. This is catered towards asphalt driveways – so if you haven’t already made the repairs here are some additional tips. 1. Clean thoroughly 2. Make sure the cracks are dry. 3. Add a backer rod to the cracks if they are large (something like this https://www.homedepot.com/p/Sika-3-4-in-Closed-Cell-Backer-Rod-108130/202523820) 4. Seal with a self-leveling concrete seal (something like this https://www.homedepot.com/p/Sikaflex-10-1-oz-Self-Leveling-Concrete-Sealant-Gray-7116070/300934515?MERCH=REC-_-PIPHorizontal2_rr-_-202523820-_-300934515-_-N)

      Just so you know, we have not used either of the products in the above links, I just grabbed them for quick examples. Sorry for the late response and good luck!

  2. I didn’t know that cracks on my driveway mean that the structure is failing. If I were to choose, I think I’ll buy Crack Filler from a good store since I was told that it was rubberized asphalt material. I’ll be sure to refill it if it’s necessary so that I can make sure that my driveway will look good as new.

  3. I didn’t realize that you have to clean asphalt cracks with a grazor before repairing them or they pull up and bubble. Good to know! My brother’s driveway is in terrible shape. I’m not sure if he needs to get it completely redone or just needs repairs, but he should probably just have a paving contractor do it so he doesn’t mess it up.

  4. Thanks for explaining that I would need to fix cracks that are bigger than 1/4 of an inch. That seems like a good thing to get a professional to help you figure out what cracks need to be repaired. Personally, I would want to get a professional with a lot of experience to help with seal coating my driveway.

  5. I totally agree with you when you said that the best thing that you can do as the owner of an asphalt driveway is to fix your cracks as soon as they appear. My neighbor likes to restore cars so he can resell them at a higher cost but he has damaged his driveway with so many oils dropped on it. I will suggest to him to contact a paving repair company so that his driveway can look new again.

  6. I have been thinking about getting an asphalt driveway this upcoming year. Thanks for explaining that it would be smart to fill any cracks with rubber. I didn’t realize that could help prevent the cracks from getting worse.

  7. My boyfriend has been complaining about the cracks and holes on our driveway because he’s worried that this might destroy his vehicle’s tires. I never knew that cracks can be addressed by blowing the crack out with compressed air flowed by a Grazor. This seems workable, but it’ll be best if we’ll just hire a seal coating service so this matter will be handled properly.

  8. You made a great point about thoroughly cleaning the cracks with a grazor that can help you get the most out of it. My husband and I are looking for an asphalt line striping service that can help mark his business parking lot. We will keep these tips in mind for when he needs a professional to help him.
