A DESIGN SUBSYSTEM FOR THE RESPONSE OF FLEXIBLE PAVEMENTS AT LOW TEMPERATURES

THIS PAPER IS BASED ON THE PREMISE THAT THE PAVEMENT DESIGN PROCESS AS A WHOLE, AND ITS COMPONENT DESIGN SUBSYSTEMS CAN BEST BE STRUCTURED AND IN TURN EVENTUALLY RATIONALIZED THROUGH A COMPREHENSIVE APPLICATION OF SYSTEMS ENGINEERING PRINCIPLES. ONE SUCH SUBSYSTEM, THAT CONCERNING THE RESPONSE OF FLEXIBLE PAVEMENTS AT LOW TEMPERATURES, IS CONSIDERED IN DETAIL IN THE PAPER. A SYSTEMS ENGINEERING FRAMEWORK IS DESCRIBED FOR STRUCTURING THE DESIGN SUBSYSTEM AND EXISTING KNOWLEDGE IS ORGANIZED WITHIN THE PHASES AND COMPONENTS OF THE FRAMEWORK. UNDER THE BASIC ASSUMPTION THAT SUSCEPTIBILITY TO CRACKING IS THE PRIMARY, UNDESIRABLE FEATURE OF LOW-TEMPERATURE PAVEMENT RESPONSE, METHODS FOR PREDICTING SUCH FRACTURE SUSCEPTIBILITY ARE CONSIDERED IN DETAIL. CURRENT RESEARCH RELATING TO MATERIALS CHARACTERIZATION TECHNIQUES FOR PROVIDING ANALYSIS INFORMATION IS DISCUSSED. IT IS DEMONSTRATED THAT ASPHALT SOURCE OR TYPE CAN HAVE A MAJOR INFLUENCE ON LOW-TEMPERATURE CRACKING OF A BITUMINOUS LAYER AND IT IS SUGGESTED THAT THIN FILM TENSION TESTING OF ASPHALTS SHOWS SOME PROMISE AS A SIMPLE AND CONVENIENT ANALYTICAL TOOL. FINALLY, IT IS RECOMMENDED THAT MORE OBJECTIVE AND COMPREHENSIVE PERFORMANCE MEASUREMENT TECHNIQUES, AND THE USE OF INFORMATION SYSTEMS, BE DEVELOPED FOR FEEDBACK INTO THE DESIGN SUBSYSTEM. /AUTHOR/
