TENSILE BEHAVIOR AND FAILURE CHARACTERISTICS OF THIN BINDER FILMS

THIS REPORT IS A PRELIMINARY INVESTIGATION INTO THE FEASIBILITY OF DEVELOPING EXPERIMENTAL TECHNIQUES, FROM WHICH INFORMATION CONCERNING THE FRACTURE PROPERTIES OF BITUMEN AND TAR BINDERS MAY BE EVALUATED. THE APPLICATION OF ELEMENTARY MODEL ANALYSIS THEORY GIVES A GREATER UNDERSTANDING OF THE TEST RESULTS IN TERMS OF ELASTIC AND DISSIPATIVE FORCES, AND ALSO ALLOWS A DESCRIPTION OF THE BEHAVIOURAL CHARACTERISTICS OF THE BINDER, BY MEANS OF SIMPLE ELASTIC AND VISCOUS COMPONENTS, IN THE BRITTLE FRACTURE AND INTERMEDIATE FAILURE REGIONS. THE MODEL PROVED TO BE INADEQUATE IN THE FLOW FAILURE REGIONS. RECOMMENDATIONS TO IMPROVE THE EXPERIMENTAL TECHNIQUES TO OBTAIN RESULTS ON A MORE QUANTITATIVE BASIS ARE PRESENTED.
