Abstract:"Saw and Seal" is the process of introducing uniformly spaced saw joints to a bituminous
overlay in an attempt to eliminate or retard the formation of thermal and /or reflective
cracking.
Saw and Seal technology has been experimented with for many years. Several states
including Connecticut, Massachusetts, New York, Minnesota and Pennsylvania have
used the Saw and Seal method. Although its primary use has been for bituminous over
jointed concrete pavements, some states are using Saw and Seal on new construction and
bituminous overlays of existing bituminous pavements. In the fall of 1997, the Maine
Department of Transportation (MDOT) completed construction on two projects which
included Saw and Seal technology in an effort to mitigate thermal and reflective cracking.
