THE "STRUCTURAL DESIGN" APPROACH TO FLEXIBLE PAVEMENT DESIGN

THE PRESENT, LARGELY EMPIRICAL, PAVEMENT DESIGN PROCEDURES USED IN SOUTHERN AFRICA HAVE LIMITATIONS, PARTICULARLY WHEN VIEWED IN THE LIGHT OF FUTURE REQUIREMENTS, A MAJOR EFFORT, IN SEVERAL COUNTRIES, IS BEING MADE TO DEVELOP A RATIONAL, STRUCTURAL DESIGN APPROACH TO THE PROBLEM WHICH WOULD AIM AT LIMITING CRITICAL STRESSES AND STRAINS IN THE PAVEMENT STRUCTURE. FOR SUCH A METHOD TO BE SUCCESSFUL, MUCH RESEARCH IS REQUIRED TO DETERMINE MATERIAL CHARACTERISTICS, TRAFFIC LOADING AND THE APPLICABILITY OF THEORETICAL ANALYSIS. WITH THE AID OF THEORY AND INFORMATION ON MATERIAL BEHAVIOUR, PARTICULARLY FATIGUE CHARACTERISTICS OF ASPHALT MIXES, IT IS POSSIBLE TO INDICATE TRENDS AND POTENTIAL WEAKNESSES IN PARTICULAR STRUCTURES. /RRL(A)/
