• Abstract:
  In an effort to compare performance and cost effectiveness of the “Saw and Seal” procedure and ; Performance Grade (PG) binders, the Maine Department of Transportation (MDOT) constructed an ; experimental project in Weston, Maine during the fall of 2000. Both the Saw and Seal method and PG ; binder are designed to minimize thermal cracking. ; Saw and Seal is the process of introducing uniformly spaced sawed joints to a bituminous overlay in an ; attempt to eliminate or retard the formation of thermal and/or reflective cracking. Several states, including ; Minnesota, New York and Massachusetts have successfully used the saw and seal process. MDOT is ; currently evaluating two saw and seal projects to determine the effectiveness of this process in ; minimizing thermal cracking. ; Performance Grade binder is a modified asphalt binder designed for use in harsh temperature conditions. ; Its application is intended to minimize thermal cracking. PG binder 58-34 is designed for a maximum ; pavement design temperature of 58 ºC and a minimum temperature of -34 ºC.
