Crack sealing is the most effective asphalt maintenance procedure when it comes to protecting and extending the life of asphalt pavement. Crack sealing prevents moisture from penetrating into asphalt cracks, freezing and causing serious deterioration and potholes. Rosemar’s experience crack sealing crew and efficient two-step process is second to none. First, cracks are cleaned using a torch and blower combination which removes debris including vegetation, leaving the surface and walls of the cracks clean and ready for treatment. After cracks are prepped, they are then filled with a blend of asphalt cement and short-length polyester fibers using a wand with a boot at the end which levels the material. This process provided an excellent waterproof membrane for cracks and joints in both asphalt and concrete pavements. Sealing pavement cracks will extend pavement life by three to five years.
