Even if your asphalt pavement was expertly installed by an experienced contractor who used the best materials, cracks will eventually develop. Your pavement takes a beating from traffic, the sun, and repeated freeze/thaw cycles, so cracks are inevitable. However, if you ignore them, cracks will continue to expand, and studies have shown that about 75% of all neglected cracks will develop potholes in less than three years. Water enters through cracks and potholes, percolates through the structure of the pavement, and erodes the foundation that gives your pavement its strength and flexibility. More cracks and potholes develop, more water enters, additional damage is done when the water freezes, and alligator cracking occurs. Before you know it, your pavement can be damaged beyond repair, leaving you no alternative other than to have it completely rebuilt. Crack sealing is an economical and long-lasting procedure that can repair cracks to help you maximize the life of your asphalt pavement.
What Is Asphalt Crack Sealing?
There are many different types of cracks that can form in asphalt pavement. Transverse cracks are those that run perpendicular to the centerline, longitudinal cracks run parallel to the centerline, seam cracks develop at pavement joints, and edge cracks form where the pavement meets a curb. A special type of cracking pattern is called alligator cracking, which involves an area of interconnected cracks that resemble an alligator’s scales. Virtually all types of cracks can be repaired through crack sealing. One notable exception is alligator cracking. Alligator cracking is almost always a sign that the foundation has been severely damaged and will need to be repaired. Foundation repair can be a costly proposition, so it is much more economical to repair cracks as soon as they develop.
• The process of crack sealing starts with a thorough cleaning of the crack to remove all gravel, vegetation, dirt, or trash that may be in the void. Unless the debris is removed, it will interfere with the bond between the pavement and the sealant material. Pressurized air is commonly used to clean out the crack, but it is sometimes necessary to use a steel brush as well.
• A motorized router may be used to make the crack’s interior walls more uniform and smoother. When the walls are smooth and even, the sealant will form a better bond. It will also be able to move with the pavement more evenly when the pavement expands and contracts.
• Because the interior of the crack needs to be free from all moisture, your contractor may use a heat lance or pressurized air to dry the space. Moisture will interfere with the establishment of a strong bond.
• A rubberized material is placed in the crack. Depending on the crack, the material may need to extend a short distance onto the surrounding pavement, but it may be completely contained within the crack.
