Best Practices for Using Asphalt Crack Fillers
Understanding Asphalt Crack Filling
Asphalt is a popular material used in the construction of pavements due to its durability and flexibility. However, over time, it is subject to cracking due to weather changes, heavy traffic, or improper installation. For this reason, it’s essential to understand how to use asphalt crack fillers to prolong the lifespan of pavements.
When to Use Asphalt Crack Fillers
The ideal time to use asphalt crack fillers is when the cracks are small and manageable. Cracks larger than 0.5 inches wide or with considerable depth may require more comprehensive repair measures. For smaller cracks, a high-quality asphalt crack filler can seal the gaps, preventing water and debris from entering the pavement’s base.

Preparing the Surface for Crack Filling
The success of using asphalt crack fillers heavily relies on surface preparation. Before applying the filler, clean the surface of any loose debris, vegetation, or dirt using a wire brush, compressed air, or a power blower. Remove any visible signs of oil or gas stains using a degreaser and rinse the surface with water. After cleaning, ensure the area is dry and free of moisture before applying the crack filler.
Choosing Quality Asphalt Crack Fillers
Choosing high-quality asphalt crack fillers is crucial to ensure the longevity of the repair. Go for fillers made of rubberized asphalt or polymers that can expand and contract with the pavement without cracking. Also, look for fillers with a low viscosity rate that can penetrate deep into the cracks and bond adequately for lasting results. Cheaper fillers may be tempting, but they are usually less effective and may require frequent re-application.
Application Process
The application process for asphalt crack fillers requires precision and accuracy to ensure proper sealing. Begin by cutting the top of the filler nozzle at a 45-degree angle to create an opening that fits the size of the crack. Then, apply the filler in a steady and continuous flow into the crack, filling it up to the surface’s level. Use a trowel to smooth the surface and ensure the filler adheres well to the pavement. Allow the filler to dry for at least 24 hours before traffic resumes to the repaired area.
Sealcoating for Added Protection
Though crack filling is an effective pavement maintenance measure, it’s not a permanent solution. The use of sealcoating can provide additional protection from UV rays, oxidation, and water penetration, extending the lifespan of the pavement. Sealcoating should be done using professional-grade materials for long-lasting results.
By following these best practices, you can enhance the performance of asphalt pavements and prolong their lifespan. Proper surface preparation, the use of high-quality fillers, and sealcoating can prevent future cracks, potholes, and other pavement damage, saving money on costly repairs and replacements.
