LAYERED SYSTEM DESIGN AS APPLIED TO CONCRETE PAVEMENTS

CONCRETE PAVEMENT PRECONDITIONED AND PRESTRESSED LAYERED SYSTEM PERFORMANCES UNDER WHEEL LOADS ARE PREDETERMINED NOT ONLY BY THE STRENGTH PROPERTIES INCORPORATED IN THE LAYERS BY CONSTRUCTION PROCEDURES, BUT MORE IMPORTANTLY BY THE CONFINING INFLUENCES OF THE RIGID CONCRETE LAYER ON THE OTHER LAYERS AND BY THE SHEARING CONTINUITY INCORPORATED BETWEEN LAYERS. THE FUNDAMENTAL PERFORMANCE CHARACTERISTICS OF CONCRETE PAVEMENT SYSTEMS ARE TREATED IN DETAIL IN ORDER TO PROVIDE ESSENTIAL BASES FOR UNDERSTANDING AND JUDGEMENTS REGARDING THE EFFECTIVENESS OF' /1/ THE REINFORCING ACTION AND LOAD SPREADING CAPACITY, /2/ THE STRESS REDUCING INFLUENCE OF THE PAVEMENT SYSTEM ON THE VERTICAL STRESSES IMPOSED IN THE SUPPORTING SUBGRADE, AND /3/ THE CAPACITY OF CONCRETE PAVEMENT SYSTEMS TO RESIST TENSILE STRESSES AND SHEAR STRESSES IN REGIONS WHICH ARE VULNERABLE TO BREAKDOWN BY BENDING AND SHEAR DEFORMATIONS. THE PRINCIPAL PROBLEMS OF DESIGN AND CONSTRUCTION OF CONCRETE PAVEMENT SYSTEMS ARE' /1/ TO LIMIT ACCUMULATED PAVEMENT SETTLEMENTS, /2/ TO ENSURE THE PAVEMENT STRUCTURE AGAINST CRACKING AND BREAKDOWN, AND /3/ TO INCREASE THE LIFE OF THE PAVEMENT STRUCTURE. DESIGN OF MULTI-LAYER CONCRETE PAVEMENT SYSTEMS TO SATISFY THESE REQUIREMENTS INVOLVE' THE DETERMINATION OF THE NUMBER OF LAYERS, THE DETERMINATION OF THEIR TENSILE STRENGTHS, SHEAR STRENGTHS AND E-VALUES, AND THE EVALUATION OF THICKNESS REQUIREMENTS FOR THESE LAYERS. THE PROBLEMS OF DESIGN AND CONSTRUCTION TO MEET THESE REQUIREMENTS ARE TREATED AND ILLUSTRATED. RECOMMENDATIONS ARE MADE FOR CONSTRUCTION METHODS AND PROCEDURE SEQUENCE TO ATTAIN SATISFACTORY PERFORMANCES AND LONG LIFE OF CONCRETE PAVEMENTS.
