Importance of Crack Filling
Asphalt is an excellent material for constructing driveways, parking lots, and other surfaces. However, it is prone to cracks due to several factors such as weathering, heavy usage, and poor maintenance, among others. When the surface cracks, water seeps down to the base and erodes it, thereby weakening the structure considerably. The situation gets worse during winter, with the freeze-thaw cycle leading to more extensive and deep cracks, potholes, or even craters. One way to fix the issue is through crack filling, an essential maintenance procedure that prevents further damage and adds to the surface’s longevity.
Timing Matters
Many factors determine the timing of crack filling, including the size and location of the crack, weather conditions, traffic volume and speed, and the age of the pavement. Before filling a crack, you must determine whether it is a working or non-working crack. A non-working crack does not expand and contract, so it is ideal to fill it as soon as possible before debris accumulates, allowing the crack to widen. In contrast, a working crack expands and contracts with varying temperatures, which makes it prone to cracking again. Waiting for the right weather conditions to fill a working crack could make the situation worse. You want to fill the working crack during the summer or early fall when the weather is dry and warm, and the crack is at its smallest. That way, you can reduce moisture ingress and the potential for the crack to grow during winter.

Frequency of Crack Filling
The National Asphalt Pavement Association (NAPA) recommends crack filling as an annual maintenance practice if the pavement has less than 20% of its surface cracked. For pavements above that range, it is advisable to fix the cracks twice a year. However, these are just general guidelines, and it is best to have an experienced pavement professional assess the pavement’s condition and recommend the most suitable maintenance program for it. Apart from crack filling, other measures such as sealcoating, pothole repair, and drainage improvements can improve the pavement’s condition and extend its lifespan.
How to Choose the Right Crack Filler
Choosing the right filler is crucial in ensuring an effective and long-lasting fix. There are several types of fillers available, including hot pour, cold pour, and polymer-modified. Hot-pour fillers are ideal for larger cracks and are heated to a high temperature and poured into the crack before cooling and hardening. Cold-pour fillers, on the other hand, come ready-to-use and do not require any heating. They are best suited for small cracks and must be applied at the right temperature, typically above 50F degree. Polymer-modified fillers combine the advantages of the two types and are best suited for high-traffic areas where the repairs must withstand vehicular stresses. Your choice of filler will depend on the crack size, Pavement condition, environmental conditions, and budget.

Conclusion
Crack filling is an essential part of pavement maintenance, and its timing and frequency are critical in ensuring the longevity and safety of the surface. Prompt filling of non-working cracks and selecting the right filling materials will reduce the damage that working cracks cause to the pavement. Hire experienced pavement contractors who understand the importance of crack filling, and follow their recommendations on maintenance frequency. With proper crack filling procedures, you can protect your pavement from degradation and ensure optimal service life.
