• Abstract:
  Sealing of cracks in asphalt surfaced pavements has long been one of the widely practiced pavement maintenance strategies by the highway agencies in including Ohio Department of Transportation. Crack sealing is performed with intent to reduce water infiltration, prevent pumping and avoid the need for premature base and pavement repair. A successful crack sealing project can result in numerous benefits such as - improved pavement condition, increased safety, extended service life, reduced maintenance and rehabilitation needs and overall, lower life cycle costs. A host of factors namely: sealing materials, placement techniques, equipment, pavement types and condition, type and severity of crack sealed, regional environmental and traffic conditions, evaluation procedures and so on are known to directly influence the level of success that can be attained in a crack sealing project. These variables often act individually or collectively to affect the outcome of a crack seal project. Despite the intended benefits, crack sealing may also affect the pavement in many ways like, tracking of sealing material by tire action, reduced skid resistance, a rougher pavement etc. Crack sealing is beneficial if pavement life is increased while maintaining serviceability.
