FEASIBILITY STUDY AND PRELIMINARY DESIGN OF A SYSTEM FOR RAPID EVALUATION OF RATIONAL PAVEMENT DESIGN

IN THIS RESEARCH REPORT, THE FEASIBILITY OF DESIGNING A TEST FACILITY FOR RAPID EVALUATION OF RATIONAL ANALYSIS OF PAVEMENT SYSTEMS IS PRESENTED. THE GEOMETRICAL AND OPERATIONAL FEATURES OF VARIOUS EXISTING FACILITIES AND THEIR INHERENT ADVANTAGES AND LIMITATIONS TO VERIFY RATIONAL PAVEMENT DESIGN THEORIES ARE DISCUSSED. THE CONCEPT OF PAVEMENT MODELING USING SIMILITUDE PRINCIPALS IS REVIEWED AND ITS APPLICATION TO THE PROBLEM UNDER INVESTIGATION IS PRESENTED. THE EFFECT OF ROLLING FRICTION ON A PAVEMENT SYSTEM IS STUDIED BY USE OF A PRISMATIC FINITE ELEMENT MODEL WHICH EVALUATES STRESSES AND STRAINS IN A HYPOTHETICAL PAVEMENT STRUCTURE. TWO TEST FACILITIES HAVE BEEN RECOMMENDED FOR USE IN VERIFICATION OF RATIONAL DESIGN THEORIES. A SENSITIVITY ANALYSIS OF VARIABLES INFLUENCING PAVEMENT LIFE HAS BEEN CARRIED OUT, AND A DESIGN OF EXPERIMENT FULFILLING THE OBJECTIVE OF THIS RESEARCH INVESTIGATION HAS VEEN DOCUMENTED. THE GEOMETRICAL AND OPERATIONAL FEATURES OF THE PROPOSED FACILITIES, PRELIMINARY DRAWINGS, AND COST ESTIMATE FOR THE CONSTRUCTION OF THE FACILITY ARE PRESENTED. /FHWA/
