Asphalt crack sealing is a process of sealing or filling cracks in the asphalt pavement to prevent water and other debris from penetrating the surface and causing further damage. It is a common form of asphalt maintenance that can help extend the life of a pavement surface.

The process of asphalt crack sealing typically involves cleaning the crevices and removing any loose debris or vegetation that may be present. A specialized sealant is then applied to the trials, filling them thoroughly to prevent water and other materials from penetrating the surface. The glue is usually a hot-poured rubberized asphalt material that bonds to the pavement and remains flexible, allowing for expansion and contraction with temperature changes.

Asphalt crack sealing is integral to pavement maintenance because cracks can allow water and other debris to penetrate the surface, leading to further damage, such as potholes, rutting, or alligator cracking. Sealing cracks early can help prevent these problems and extend the life of the pavement.

In addition to preventing further damage, asphalt crack sealing can also improve the appearance of the pavement surface. The sealant fills in the cracks and creates a smooth, uniform surface that can enhance the safety and aesthetics of the area.

The frequency of asphalt crack sealing depends on several factors, including the age and condition of the pavement, the climate and weather conditions in the area, and the amount of traffic the pavement receives. In general, it is recommended that cracks be sealed as soon as they are detected to prevent further damage and extend the life of the pavement surface.
