CRACK SEALING
Filling of cracks and joints has been a maintenance and construction industry function for many years. The traditional filling approach has recently been challenged by the sealant approach. Today's technology has greatly improved sealant materials and methods for sealing cracks and joints in a more cost effective and preventative way.
For long-term crack seal performance, between five and eight years, a standard or low-modulus rubberised asphalt sealant installed in either a standard or shallow recessed band-aid configuration should be used. These materials provide a high level of flexibility and adhesiveness to accommodate annual crack movement. Moreover, the combination of a reservoir and an overband helps to maximise sealant performance. Life cycle costs show that by utilising either crack sealing configuration B or C, the cost of crack sealing is 50% less than that of using configuration D.
* Proper crack sealing will last five to eight years.
* Routing and sealing with a band-aid configuration will extend the life of the sealant more than 50%.
* The use of a high quality sealant is mandatory if you want extended pavement life.
This sealing breakthrough means that we can extend the life of our nation's roadway system, parking lots, airport pavement systems and pavements in general. After all, at today's prices, it's cheaper to repair and maintain.
