SEALING CONCRETE PAVEMENT JOINTS FOR ZERO MAINTENANCE

The report recommends the use of a sealant that satisfies ASTMD 34-6-75T with frequent joints, adequate joint configuration and good installation practices. This specification (Tentative Specification for Joint Sealants, Hot-poured, Elastomeric Type, for Portland Cement Concrete Pavements) includes a resiliency requirement as a measure of ability to reject incompressibles, allows no flow at 158 deg F and has an artifical weathering test requirement to indicate life expectancy. The joint shape factor, and sealant installation and joint cleaning are discussed. The use of a premium joint sealant properly applied into a reservoir correctly designed, spaced and cleaned will produce a zero-maintenance joint. An owner may now require an extended warranty that the sealant will keep water and incompressibles out of the joint for a minimum period of 10 years. This has been accomplished at commercial and military airports as well as major toll highway facilities.
