FIELD STUDY OF PERFORMANCE AND COST OF A COMPOSITE PAVEMENT CONSISTING OF PRESTRESSED CONCRETE PANELS INTERCONNECTED AND COVERED WITH ASPHALTIC CONCRETE

THIS REPORT DESCRIBES THE DESIGN, CONSTRUCTION, AND FIELD TESTING OF A NEW CONCEPT IN HIGHWAY PAVEMENT DESIGN--A COMPOSITE OF FAVORABLE FEATURES OF BOTH RIGID AND FLEXIBLE PAVEMENTS CONSISTING OF PREFABRICATED PRESTRESSED CONCRETE STRUCTURAL COMPONENTS COVERED WITH A LEVELING COURSE OF ASPHALTIC CONCRETE. THE PRESTRESSED STRUCTURAL PANELS ARE PLACED ON THE PREPARED ROADBED AND INTERCONNECTED WITH SPECIAL STEEL CONNECTORS AND GROUT KEYS. THE PANELS PRODUCE THE STRUCTURAL EFFECTS OF A SPREAD FOOTING, YET POSSESS A HIGH DEGREE OF FLEXIBILITY AND RESISTANCE TO PERMANENT CRACKING. THE ASPHALT LEVELING COURSE FURNISHES A FLEXIBLE AND WATERPROOF SURFACE WITH EXCELLENT RIDING CHARACTERISTICS. DESIGN DETAILS, CONSTRUCTION COSTS, AND FIELD TESTS FOR AN EVALUATION OF STRUCTURAL PERFORMANCE ARE INCLUDED AND DISCUSSED IN VIEW OF THE SHORT PERIOD OF THE FIELD PERFORMANCE STUDY. /AUTHOR/
