When it comes to repairing asphalt, many homeowners and business owners assume that any fix is a good fix. Unfortunately, this isn’t always the case! If you’re not careful, you can invite potholes, cracks, and other damage.
It all comes down to preparing the surface correctly before patching. Whether sweeping the dirt and debris away or heating the asphalt so the patching material will adhere, taking the time to do things correctly will save you a lot of headaches (and money).
Don’t let a lousy patch job ruin your asphalt!
Quick Compaction Cooling:
The key is to remember that you’re working with two materials: asphalt and the patching material. The bond between the two will hold everything together, so it’s essential to give that bond time to form.
If the bond cools down prematurely, it will result in a brittle repair that won’t last. Reheat the targeted region for 1 to 2 minutes with the infrared heat gun before compressing it.
Not Watching the Weather:
Keeping an eye on the weather when working with asphalt is essential. If it’s too hot, the asphalt can soften, and your repair will be compromised. If it’s too cold, the asphalt won’t set correctly, and you’ll have a crumbly mess.
The ideal patching weather is between 60 and 80 degrees Fahrenheit. Therefore, it’s important to schedule your projects accordingly.
Not Every Technique is Right:
There are different asphalt patching techniques, each with advantages and disadvantages. Throw-and-roll patches are the quickest and easiest to apply. However, they’re also the least durable.
Spray injection patches are more expensive but will last longer. Conversely, full-depth patches are the most expensive but will last the longest.
Once is Never Enough:
A common mistake people make is expecting one patch to do the trick. Unfortunately, this is rarely the case. Asphalt surfaces are constantly expanding and contracting due to temperature changes. This movement can cause even the best patch job to fail.
That’s why it’s vital to monitor patched areas closely. If you see any cracks or gaps, you’ll need to patch them again.
How to Prepare an Asphalt Surface for Patching:
Preparing the surface is critical to the success of your repair. Hasty jobs can lead to uneven surfaces and a shorter lifespan for your patch.
To properly prepare an asphalt surface:
Clean the Surface Properly:
You’ll need to remove any dirt, debris, or loose asphalt. A power washer can be helpful in this step. Next, use a putty knife or trowel to remove any remaining debris from cracks or crevices.
Fill Cracks and Holes:
Potholes and cracks are an asphalt surface’s worst enemy. Filling these cracks and holes will help extend the life of your repair. Use a cold patch filler or hot asphalt to fill cracks or holes.
Apply a Primer:
Applying a primer will help the patch to better adhere to the surface. You can use a sprayer, a roller, or a brush to apply the primer.
