Sealing cracks is an essential preventative maintenance service that helps extend the life of asphalt pavement. It can also help protect the underlying concrete and minimize the need for costly repair or replacement. The success of a crack seal service project depends on how well the contractor prepares the pavement before applying sealant. It also depends on the quality of the adhesive chosen.
Before crack sealing, it is essential to prepare the pavement surface. This includes removing debris and vegetation, which can impede the proper adherence of the crack seal material.
Routing the crack is one of the most effective methods of preparing the surface for sealing. This method creates a channel that allows the material to expand and contract evenly under various environmental conditions.
It is also necessary to clean the crack channel thoroughly of loose aggregate and sand. This can be achieved by blowing high-pressure dry, clean air into the crack with a hot air lance.
It is also essential to consider asphalt paving seattle recommended by the manufacturer, usually between 380 and 410 degrees Fahrenheit. Overheating the adhesive degrades its properties, while under-heating it negatively affects adhesion.
A little TLC goes a long way regarding a successful crack seal service. One of the most critical factors in getting the job done is ensuring that the materials are dry and moisture-free and that the process is appropriately documented in writing. The best way to ensure this is the case is by keeping the area free of debris as much as possible and avoiding the temptation to apply the seal over it. The other major step is using the correct crack sealant to prevent sag. The result is a quality repair that will last for years to come.
Whether sealing cracks, applying seal coat, or line striping paint, the temperature of your job site is crucial to the work's success. Temperature ensures the material adheres to the asphalt surface and that air leakage is minimized.
The ideal temperature for sealant application is warm enough to achieve a desirable bond between the sealant and asphalt but not so hot that it burns. This is why many pavement contractors prefer to use a double boiler melter, which evenly heats and agitates the sealant material.
Using a hot air lance to clean the cracks of debris, dirt, and moisture is also helpful. However, water and other contaminants can interfere with the material's ability to bond properly with the asphalt.
Having a crack seal service repair team with the most up-to-date safety equipment and training is critical to the success of any road project. The right equipment is also required to handle the hot, rubberized sealant.
The safest way to get the job done is to hire a crack seal contractor that can handle the entire process from paving to application, ensuring a smooth operation. Having a skilled crew that can do it all will save your company money and time in the long run.
The best time to do a crack seal service repair is during the spring or fall when weather conditions are moderate, and asphalt surfaces are in the best shape. The right products and tools can ensure a smooth and successful job that will last for years. The right technology will even help you track the best times to seal and identify the most effective routes to complete the task with minimal disruption.
