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 that included Saw and Seal technology in an effort to mitigate thermal and reflective cracking
