How to Repair Driveway Cracks

August 30, 2019

When you first laid down your asphalt driveway, it likely looked smooth and jet black, and was perfect to drive on. While asphalt does last a long time and is a great choice for driveways, it is common for the material to develop cracks and fissures over time. Tending to these cracks in a timely manner before they become worse is important for avoiding more costly driveway repair in Des Moines, IA. Fortunately, repairing cracks doesn’t take much time or money, and you can do it yourself. Read on to learn more!

Preparing the surface

Before you begin to fix the cracks, you’ll want to prepare your asphalt. Make sure the area is as clean and smooth as possible so that your patching material adheres to the surface. You can do this in several ways. Before beginning your driveway repair in Des Moines, IA, use a hammer and chisel to remove broken pieces of asphalt that might be in the way of the crack. You can also use a wire brush to remove debris from the crack and create a smooth surface. An air gun or shop vacuum can also be useful in removing smaller debris from inside the crack, and a hose can completely flush out the crack for a smooth surface. Then, depending on the size of the crack, you’re ready to begin patching.

Fixing small cracks

If your asphalt has only small cracks, your driveway repair in Des Moines, IA will be simple. Use a rubberized asphalt emulsion crack filler to fill in the smaller cracks that are between 1/8 and 1/2 inch wide. Try to avoid getting the filler onto non-damaged areas of the driveway. You can apply the filler with a caulking gun if you have one, or pour it directly into the crack with caution. A putty knife or trowel will be useful in smoothing the surface of the crack. You should let the filler dry completely according to the instructions from the manufacturer before driving or putting weight on the surface.

Fixing larger cracks

Fixing larger cracks in your asphalt can be more time consuming. If the crack you are fixing is more than two inches, you’ll want to first fill in the crack up to the two-inch mark with small, crushed, angular gravel. Pea gravel and large gravel can shift frequently and do not provide a stable base. Then, press the gravel down, compacting it with a wooden post or steel tamper. Once you’ve sufficiently filled in the hole, you’ll need to fill the crack with a cold process asphalt repair compound, such as blacktop, compact it again, then add more blacktop as needed until it’s level.
