Why is Asphalt Crack Filling Important?

Asphalt is a durable and reliable pavement material, but it can still develop cracks over time. Crack filling is an essential maintenance task for an asphalt pavement, as it helps prevent water and debris from penetrating the cracks and damaging the subbase and underlayment, which could result in more significant and costly repairs. Crack filling can also improve the appearance of the pavement, reduce the risk of tripping hazards, and prolong the lifespan of the pavement.

When to Fill Asphalt Cracks?

The best time to fill asphalt cracks is when they are still small, typically less than a quarter-inch wide. Waiting too long to address the cracks could result in the need for more extensive and expensive repairs. Asphalt cracks can be caused by many factors such as weather, traffic loads, and improper installation. It’s essential to inspect the pavement regularly to identify any cracks early and address them before they become larger.

Choosing the Right Asphalt Crack Filler

Choosing the right type of asphalt crack filler can have a significant impact on the quality and durability of the repair. There are different types of crack fillers available on the market, such as hot-pour and cold-pour sealants. Hot-pour sealants are usually applied with a melter and are best suited for large and deep cracks, while cold-pour sealants are easier to apply and are ideal for small and narrow cracks. It’s important to select a high-quality asphalt crack filler that meets the pavement’s specific needs and environmental conditions.

How to Apply Asphalt Crack Filler?

To ensure that the crack filling process is successful, there are several best practices that should be followed, including:

  • Preparing the area: The pavement should be thoroughly cleaned and dried before applying the crack filler. Remove any water, dirt, vegetation, or debris from the crack using a wire brush, broom, or compressed air.
  • Temperature: Check the temperature of the pavement and the crack filler to ensure they are both within the recommended range. Most crack fillers require the pavement temperature to be above 50°F for proper adhesion.
  • Application: Fill the crack with the crack filler using a pour pot or a pump system. Make sure to fill the crack from the bottom up, leaving a small space at the top for expansion. Use a squeegee or a trowel to spread the crack filler evenly and remove any excess material. Allow the crack filler to dry and cure according to the manufacturer’s instructions.
  • Post-application: Clean any tools or equipment used for the application with a solvent, such as mineral spirits or lacquer thinner. Seal the crack with a coat of sealcoat to protect the filler from weathering and traffic and help blend in with the surrounding pavement.
  • Maintaining the Asphalt Pavement

    Crack filling is just one aspect of an asphalt pavement maintenance plan. Regular inspections, sweeping, sealcoating, and crack sealing are all critical to keeping the pavement in good condition and prolonging its lifespan. A well-maintained pavement not only provides a safer and smoother driving surface but also reduces the overall maintenance cost.


    Crack filling is an essential maintenance task for an asphalt pavement. By understanding the importance of crack filling and following the best practices, you can ensure that the pavement is protected, the appearance is improved, and the lifespan is extended, thus saving costs over time. Remember to choose the right crack filler, prepare the area correctly, apply it properly, and maintain the pavement regularly to enjoy the benefits of a well-maintained pavement.
