ECONOMICS OF RESURFACING DISINTEGRATED PAVEMENTS

FACTORS INVOLVED IN AN ECONOMIC STUDY OF THE RESURFACING OF DISINTEGRATED PAVEMENTS ARE DISCUSSED. TO JUSTIFY RESURFACING, ITEMS CONSIDERED MUST BE: AGE OF THE PAVEMENT, WIDTH OF THE PAVEMENT, SLAB DESIGN, TRAFFIC LOAD CARRIED, ALIGNMENT AND GRADE OF THE EXISTING PAVEMENT. THE DEMANDS FOR HIGHWAY IMPROVEMENTS IN PENNSYLVANIA HAVE REACHED THE POINT WHERE FINANCES WILL NOT PERMIT RECONSTRUCTION AS RAPIDLY AS TRAFFIC DEMANDS. THEREFORE, IT IS NECESSARY TO CONSIDER REHABILITATION RATHER THAN RECONSTRUCTION SINCE REHABILITATION CAN BE UNDERTAKEN AT APPROXIMATELY ONE-HALF TO ONE-THIRD THE COST OF RECONSTRUCTION. THE REHABILITATION PROGRAM CONSISTS OF FOUR TYPES OF WORK: (1) RESURFACING THE EXISTING PAVEMENT, WHICH CONSISTS OF REPAIRING THE EXISTING BASE COURSE (CONCRETE OR MACADAM) AND PLACING A NEW WEARING SURFACE, (2) PLACING ADDITIONAL DEPTH OF BASE ON THE EXISTING PAVEMENT AND PLACING A NEW SURFACE, (3) WIDENING AND REPAIRING THE EXISTING PAVEMENT AND PLACING A NEW SURFACE, AND (4) SUBSEALING AND REPAIRING THE EXISTING PAVEMENT AND PLACING A NEW SURFACE THEREON. THIS REHABILITATION PROGRAM HAS ENABLED PENNSYLVANIA TO KEEP MAINTENANCE COSTS WITHIN REASONABLE LIMITS. THE MAXIMUM SALVAGING OF PRESENT PAVEMENTS BY RESURFACING APPEARS TO BE THE ONLY METHOD WHEREBY SATISFACTORY USE OF THE HIGHWAY TRANSPORTATION SYSTEM CAN BE ACHIEVED ECONOMICALLY.
