When Is It Time to Begin a Crack Sealing Project?

Cracks in pavement are more than just an eyesore; they can be the beginning of more severe damage if not addressed promptly. Crack sealing is an essential maintenance activity that can extend the life of your pavement and save you money in the long run. But how do you know when it’s time to start a crack sealing project? Here are the key indicators and factors to consider.

1. Visible Cracks and Their Types

The most obvious sign that it’s time to begin a crack sealing project is the presence of visible cracks on the surface of your pavement. Not all cracks are created equal, and understanding the types can help determine the urgency of the project.

• Transverse Cracks: These cracks run perpendicular to the pavement’s centerline and are usually caused by temperature fluctuations.
• Longitudinal Cracks: These run parallel to the centerline and are often the result of poorly constructed joints or aging.
• Block Cracks: These form a square or rectangular pattern and indicate a failure of the asphalt binder to expand and contract with temperature changes.
• Alligator Cracks: Resembling the skin of an alligator, these are a sign of severe structural failure and indicate a need for more than just crack sealing.

2. Seasonal Considerations

Timing is crucial when planning a crack sealing project. Traditionally, the best time to seal cracks is during the spring or fall when temperatures are moderate.

That’s where LAB Manufacturing’s Hot Air Lances come in to save the day. Operators can now remove debris, dry and warm pavement surfaces prior to application during the coldest of months. This is made possible with an LA*B Hot Air Lance, which are capable of reaching temperatures of up to 3000°F.

3. Weather Conditions

Ideal weather conditions are necessary for a successful crack sealing project. The pavement cracks need to be dry and clean. Rain can prevent the sealant from adhering properly, and dirt or debris in the cracks can compromise the effectiveness of the seal. With a Hot Air Lance you don’t have to wait to get your work done after a recent rainfall.

4. Pavement Age and Condition

Older pavements are more likely to have developed cracks due to wear and tear. If your pavement is over 5-7 years old, regular inspections are essential. Even if cracks are not yet visible, preventive crack sealing can be beneficial.

5. Traffic Load

High traffic areas are more susceptible to cracking due to the constant pressure and movement. If your pavement sees heavy traffic, more frequent crack sealing may be necessary to maintain its integrity.

6. Past Maintenance Records

Keeping a record of past maintenance activities can help predict when future crack sealing might be needed. If it has been several years since the last crack sealing, it might be time to inspect and potentially seal any new cracks that have developed.

7. Budget Considerations

While budget constraints can delay maintenance activities, it’s essential to consider the long-term costs. Delaying crack sealing can lead to more extensive damage, requiring more expensive repairs or even complete pavement replacement.

Conclusion

Crack sealing is a critical maintenance task that can significantly extend the life of your pavement. By paying attention to visible cracks, seasonal and weather conditions, pavement age, traffic load, and maintenance history, you can determine the optimal time to start a crack sealing project. Regular inspections and timely interventions can save you money and keep your pavement in excellent condition.
