A SYSTEMS ANALYSIS OF THE HIGHWAY PAVEMENT DESIGN PROCESS

EXISTING PAVEMENT DESIGN PROCEDURES ARE REVIEWED AND THE CURRENT PHILOSOPHY OF PAVEMENT DESIGN AND THE DEFICIENCIES OF THESE METHODS ARE DISCUSSED. A SYSTEMS ANALYSIS OF THE HIGHWAY PAVEMENT DESIGN PROCESS IS PRESENTED, WITH SOME OF THE REQUIREMENTS PERTINENT TO A SENSITIVITY ANALYSIS OF THE PROCESS. EACH OF THE ELEMENTS OF THIS PROCESS IS DEFINED AND METHODS SUGGESTED FOR ORGANIZING EXISTING INFORMATION ON EACH OF THESE ELEMENTS. METHODS ARE SUGGESTED FOR THE SYSTEMATIC COLLECTION OF INFORMATION, ITS STORAGE, RETRIEVAL, AND ANALYSIS. IT IS CONCLUDED THAT THE DEVELOPMENT OF A RATIONAL HIGHWAY PAVEMENT DESIGN PROCESS REQUIRES THE ABILITY TO PREDICT THE PAVEMENT'S SERVICEABILITY-AGE HISTORY OF A POTENTIAL HIGHWAY PAVEMENT DESIGN UNDER THE EXPECTED TRAFFIC LOADINGS, THE CLIMATIC CONDITIONS, AND THE COST STREAMS NECESSARY TO PRODUCE THIS SERVICEABILITY PROFILE. THE PRINCIPAL PHASES OF THE SYSTEMS ANALYSIS ARE: PROBLEM DEFINITION, SOLUTION GENERATION, SOLUTION ANALYSIS, EVALUATION AND OPTIMIZATION, IMPLEMENTATION, AND PERFORMANCE ASSESSMENT. SYSTEMATIC FIELD PERFORMANCE STUDIES IN CANADA HAVE INDICATED THAT PAVEMENTS THAT ARE ADEQUATELY PROPORTIONED TO CARRY TRAFFIC LOADINGS WILL DETERIORATE DUE TO NONLOAD ASSOCIATED FACTORS. THE PRIMARY DEFICIENCIES IN CURRENT KNOWLEDGE REGARDING PAVEMENT STRUCTURES ARE CONSIDERED TO LIE IN THE AREAS OF FIELD PERFORMANCE EVALUATION AND QUALITY CONTROL.
