CRACK SEALING Sealing cracks in asphalt pavement is a commonly used maintenance procedure which reduces pavement deterioration by eliminating surface water penetration into underlying base and sub-base layers. Cracks left untreated will lead to more cracks, alligator cracking, potholes and sub-base failure.

Crack Sealing is one of the most cost-effective pavement preservation tools available. Potholes and additional cracks will form at 80% of unsealed cracks versus 1% of sealed cracks. Progressive pavement managers are recognizing these statistics and the value added to the pavement condition. Crack Sealing is a very important tool for any pavement management program.

NYBIT has found the AC & Fiber (asphalt cement and polyester fiber) Crack Sealing method the most effective. With self-contained 1000 gallon units, the cracks are cleaned with air blasting and the sealant is extruded by pressure into the crack. The polyester fiber adds strength to the sealant which in turn increases pavement life. Compared with the smaller equipment the self-contained 1000 gallon extruders enable unmatched production.

ADVANTAGES

• Keeps surface water from weakening subbase
• Eliminates hydroplaning and increases skid resistance
• Slows the PCI deterioration rate
• 2 to 5 year pavement life extension
• Excellent cost benefit ratio
• Prevents cracks from developing into potholes
