How to Properly Fill Cracks in Asphalt

Understanding the Importance of Crack Filling

Asphalt is an incredibly durable material commonly used for constructing roadways, parking lots, and driveways. However, over time, it is natural for cracks to develop due to various factors such as temperature fluctuations and heavy traffic. These cracks not only compromise the integrity of the asphalt surface but also allow water and other contaminants to seep through, leading to further damage and deterioration. That is why proper crack filling is crucial to maintaining the longevity and functionality of your asphalt pavement.

Preparing the Crack for Filling

Before you can start filling the cracks in your asphalt, it is essential to prepare the surface properly.

Start by thoroughly cleaning the area using a broom or brush to remove any loose debris, dirt, and vegetation. A clean crack ensures better adhesion of the crack filler.

For larger cracks, you may need to use a pressure washer to remove any stubborn dirt or debris trapped inside.

Next, use a wire brush or chisel to remove any loose pieces or chunks around the crack edges. This will create a clean surface for the crack filler to adhere to.

If the cracks are deeper than half an inch, it is recommended to use a crack filler specifically designed for deeper cracks. These fillers are usually made of rubberized asphalt or modified acrylic.

Choosing the Right Crack Filler

When it comes to crack fillers, there are several options available in the market. It is crucial to choose the right one depending on the size and severity of the cracks.

For small cracks less than a quarter-inch wide, liquid crack sealants are a popular choice. These sealants come in a bottle with an applicator tip, making it easy to apply directly into the crack.

For medium-sized cracks up to half an inch wide, rubberized asphalt crack fillers are an excellent option. They are easy to use, provide good adhesion, and can withstand temperature fluctuations without cracking or melting.

For larger cracks over half an inch wide, a cold patch asphalt repair compound is the most suitable choice. These compounds come in a solid form and can be applied using a trowel or shovel. They are designed to provide a more permanent repair for deep and wide cracks.

Applying the Crack Filler

Once you have selected the appropriate crack filler for your asphalt, it is time to apply it to the cracks.

For liquid crack sealants, simply cut the applicator tip to the desired size and start filling the crack from the bottom to the top. Make sure to fill the crack completely, slightly overfilling it to account for settling. Use a squeegee or trowel to level the filler and smooth out the surface.

For rubberized asphalt crack fillers, you can use a caulking gun or pour the filler directly into the crack. Then, use a trowel to spread and compact the filler. Again, make sure to slightly overfill the crack to allow for settling and use the trowel to create a smooth surface.

For cold patch asphalt repair compounds, simply pour the material into the crack and use a trowel or shovel to compact it. Make sure to follow the manufacturer’s instructions for proper application and curing time.

Protecting and Maintaining the Repaired Area

After filling the cracks in your asphalt, it is crucial to protect and maintain the repaired area to ensure its longevity.

Allow the crack filler to cure completely before allowing any traffic on the repaired area. This can take anywhere from a few hours to a few days, depending on the type of filler used.

Regularly inspect the repaired area for any signs of damage or new cracks. Address any issues promptly to prevent further deterioration.

Implement a routine maintenance plan for your asphalt pavement, including regular sweeping and cleaning, crack filling as needed, and sealcoating every few years to protect against UV rays and water damage.

By following these steps and best practices, you can ensure that the cracks in your asphalt are properly filled, extending the life of your pavement and maintaining a smooth and safe surface for years to come.
