Maintaining asphalt in good condition requires addressing issues promptly. Even small cracks should be repaired immediately to prevent them from expanding and causing more extensive damage. However, it's essential to understand the difference between crack filling and crack sealing to ensure the correct solution is applied. This knowledge will not only help you avoid costly mistakes but also enable you to confidently explain the best approach to your clients.
Crack Filling
Crack filling is used for larger, non-working cracks and holes that don't require the flexibility of crack sealing. These cracks are typically less than 0.10 inches wide and include types such as block, longitudinal, or diagonal cracks. Because the edges of these cracks remain close together, there is minimal movement, making crack filling the ideal solution.
Crack filling involves using cold-patch or hot-patch asphalt to fill the crack. It is a durable, more permanent solution, especially for deeper and wider cracks that require more substantial repairs. The materials used for crack filling aren't rubberized, as minimal flexibility is necessary. This method is often more straightforward, requiring fewer tools: a shovel, tamper, pressurized air, and the patch mix are typically sufficient for the job.
Crack Sealing
Crack sealing is ideal for smaller, active cracks that are still in their early stages. This process involves injecting hot sealant into or above the crack to prevent water from penetrating and reaching the subgrade, which could worsen the damage. Sealing is used to stop the crack from growing larger and causing more significant issues.
While crack sealing is a faster process, it requires more specialized equipment, such as tanks, melt pots, and torches, to properly apply the hot sealant. Sealing is typically used for cracks that are less than three-quarters of an inch wide. If the crack exceeds this size, filling is the better choice, as the sealant won't adhere effectively to larger gaps. Though crack sealing requires a larger investment due to the necessary tools and materials, it provides a longer-lasting solution, offering better protection and a higher return on investment compared to crack filling.
Which Solution is Right for You?
Deciding whether to use crack filling or crack sealing depends on the size and condition of the cracks. For larger, more stable cracks, filling provides a permanent solution. For smaller, active cracks, sealing is the best approach to prevent further damage and maintain the integrity of your asphalt.
