Best Practices for Using an Asphalt Crack Machine 1

Understanding the Importance of Asphalt Crack Repair

Asphalt is a commonly used material for road construction due to its durability and flexibility. However, over time, asphalt surfaces can develop cracks due to various factors such as weathering, traffic load, and subpar installation. These cracks not only deteriorate the appearance of the road but also compromise its structural integrity. To prevent further damage and maintain the longevity of the asphalt surface, it is crucial to effectively repair these cracks using an asphalt crack machine.

Choosing the Right Asphalt Crack Machine

When it comes to crack repair, the choice of the right asphalt crack machine plays a vital role in achieving optimal results. There are various types of machines available in the market, ranging from handheld units to large-scale models. Factors such as the size of the project, the severity and size of the cracks, and the available budget should be considered while selecting the machine.

For small-scale crack repair projects, a handheld crack machine is often sufficient. These machines are lightweight and portable, allowing for easy maneuverability. However, for larger-scale projects, such as highways or parking lots, a larger, self-propelled crack sealing machine may be necessary. These machines offer increased efficiency and productivity, enabling faster completion of the repair process.

Preparing the Crack for Repair

Before initiating the crack repair process, proper preparation of the crack is crucial to ensure a successful outcome. Brooming or blowing out the crack using a high-powered blower removes any loose debris, dirt, or vegetation that may hinder the adhesion of the sealant.

If the crack has accumulated moisture, it is essential to dry it thoroughly before proceeding with the repair. Moisture can affect the effectiveness of the sealant and hinder its bonding with the asphalt surface. Using a heat lance or a hot air lance is an effective way to remove moisture from the crack.

Sealing the Cracks with Precision

Once the crack has been properly prepared, it is time to seal it using an asphalt crack machine. The machine uses heat to melt the sealant and applies it to the crack with precision. It is important to apply the sealant not only to the surface of the crack but also to the sidewalls. This ensures a complete and thorough seal, preventing further water infiltration and the expansion of the crack.

It is crucial to maintain a consistent temperature while using the asphalt crack machine. The temperature of the sealant should be carefully monitored to ensure it remains within the recommended range specified by the manufacturer. This helps to achieve optimal flow and adhesion of the sealant, resulting in a durable and long-lasting repair.

Protecting the Repaired Crack

After the crack has been sealed, it is important to provide adequate protection to ensure the longevity of the repair. Placing traffic cones or barricades around the repaired area prevents vehicular traffic from disturbing the sealant before it has fully cured. It is recommended to allow the sealant to cure for at least 24 hours before re-opening the repaired section to traffic.

Regular maintenance is crucial to extend the lifespan of the repaired crack. Inspecting the sealed crack periodically and addressing any emerging issues promptly can prevent it from deteriorating further. Additionally, applying a sealcoat to the entire asphalt surface can help protect it from future cracks and deterioration.


Proper crack repair using an asphalt crack machine is essential for maintaining the integrity and aesthetics of asphalt surfaces. By understanding the importance of crack repair, choosing the right machine, preparing the crack correctly, sealing it with precision, and providing adequate post-repair protection, one can achieve effective and long-lasting results. Regular maintenance and preventative measures can further enhance the lifespan of the repaired crack and ensure the longevity of the asphalt surface.
