WHAT WE HAVE LEARNED TO DATE FROM EXPERIMENTAL CONCRETE SHOULDER PROJECTS

CONCRETE SHOULDERS HAVE BEEN IN USE ON URBAN EXPRESSWAYS IN SOME AREAS FOR YEARS. THEY ARE NOW COMING INTO USE FOR MAJOR RURAL HIGHWAYS AS WELL. SEVERAL EXPERIMENTAL PROJECTS, MOST OF THEM INITIATED UNDER THE FHWA NATIONAL EXPERIMENTAL AND EVALUATION PROGRAM, HAVE BEEN BUILT IN RECENT YEARS, AND MORE ARE UNDER CONSTRUCTION OR PLANNED. THE PAPER SUMMARIZES PERFORMANCE TO DATE, EXAMINES DESIGN DETAILS DEVELOPED FROM EXPERIMENTAL PROJECTS, AND MAKES RECOMMENDATIONS FOR DESIGN FOR MAXIMUM SAFETY AND ECONOMY. THE PAPER SUGGESTS THAT FURTHER STUDY SHOULD BE GIVEN TO (A) EFFECTS ON TEMPERATURE AND MOISTURE CONDITIONS WITHIN THE PAVEMENT SYSTEM AS THE RESULT OF A LIGHT-COLORED SHOULDER SURFACE AND (B) EFFECT ON STRUCTURAL CAPACITY ON A CONCRETE ROADWAY PAVEMENT WHEN A TIED AND KEYED CONCRETE SHOULDER IS ADDED.
