DESIGN CONSIDERATIONS FOR RESURFACING PAVEMENTS WITH CONCRETE

THE MOST COMMON METHODS FOR DETERMINING CONCRETE RESURFACING THICKNESS ARE REVIEWED, AND THE MAJOR FACTORS AFFECTING THE DESIGN OF CONCRETE RESURFACING ARE DISCUSSED. IT IS SUGGESTED THAT LIMITATION OF SLAB DEFLECTION IS OF GREAT IMPORTANCE. DEFLECTION AT JOINTS, CRACKS, AND FREE EDGES IS GREATER THAN DEFLECTION AT SOME DISTANCE FROM THOSE DISCONTINUITIES. BASED ON LABORATORY DATA, MAXIMUM SLAB DEFLECTION FOR VARIOUS METHODS OF LOAD TRANSFER ACROSS JOINTS OR CRACKS IS PROPOSED. THE METHODS OF LOAD TRANSFER DISCUSSED ARE AGGREGATE-INTERLOCK, DOWELS, AND CONTINUOUS REINFORCEMENT. THE EFFECT OF LOAD POSITION AND METHOD OF LOAD TRANSFER ON SLAB DEFLECTION IS NOTED, AND THE STRUCTURAL BENEFIT OF TIED CONCRETE SHOULDERS IS INDICATED. VALUES FOR THE SLAB SUPPORT CAPACITY OF SUBGRADES, SUBBASES, AND EXISTING PAVEMENTS ARE SUGGESTED, AND, BASED ON CONCRETE PAVEMENT PERFORMANCE AT THE AASHO ROAD TEST, MAXIMUM ALLOWABLE SLAB DEFLECTION WAS CALCULATED TO BE 0.025 IN. EQUATING SLAB DEPTHS DETERMINED BY CALCULATION AND FIELD PERFORMANCE MADE IT POSSIBLE TO ESTABLISH A RELATION BETWEEN STATIC LOADS AND TRUCK TRAFFIC. CONCRETE RESURFACING THICKNESS WAS THEN RELATED TO TRUCK TRAFFIC, METHOD OF LOAD TRANSFER ACROSS TRANSVERSE JOINTS OR CRACKS, SHOULDER TYPE, AND SLAB SUPPORT. A DESIGN EXAMPLE IS USED TO ILLUSTRATE HOW CONCRETE RESURFACING THICKNESS MAY BE DETERMINED. THE DESIGN AND PERFORMANCE OF SOME RECENT CONCRETE RESURFACING PROJECTS ARE CONSIDERED. THE NEED FOR A STRESS RELIEF OR LEVELING COURSE FOR CONCRETE RESURFACING OF BOTH CONCRETE AND BITUMINOUS PAVEMENT IS DISCUSSED. THE USE OF THE PCA ROADMETER TO DETERMINE PRESENT SERVICEABILITY INDEX AND ITS APPLICATION TO CONCRETE PAVEMENT AND RESURFACING DESIGN ARE INDICATED.
