Common small surface distresses, especially cracks and deterioration around joints can, if not treated, cause problems that can eventually require more costly repairs. Crack sealing is the first line of defense in protecting Colorado's asphalt surfaces.
Crack Repair and Sealing
At the first sign of light to moderate distress, a program of pavement preservation should be undertaken to protect your pavement investment. Asphalt cement, fibers and flexible rubberized asphalt sealants bond to crack walls and move with the pavement, preventing water from entering. This extends the pavement life and greatly reduces maintenance cost.
Random Crack Repair
The Random Crack Repair process uses compressed air and a high-pressure blow pipe to remove dirt, debris, and water. A melting kettle heats the crack sealant compound to liquid form, which is then delivered to the pavement surface through a pressure hose line and applicator shoe. The shoe width and sealer overbanding area are two to four inches wide. When traffic requires immediate use of the roadway, materials can be applied over the repaired crack to prevent sealer pickup. Crack sealing is a critical line of defense against water infiltration. In the winter months, infiltration occurs during any ground thaw or during a thaw induced by the application of de-icers.
