Back to Services   Back to Services 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. Florida Highway Products 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.
