RESEARCH ON ASPHALTIC MATERIALS--TERMINAL REPORT

THIS TERMINAL REPORT INCLUDES SUMMARIES OF REPORTS OF A 6-YEAR LABORATORY STUDY OF SELECTED ASPHALT CEMENTS. INCLUDED IS AN UPDATING OF BASIC RHEOLOGICAL AND COMPOSITIONAL INFORMATION ON SEVERAL ASPHALTS AND A RHEOLOGICAL EVALUATION DEVELOPED USING AN INSTRON EXTRUSION TECHNIQUE. RHEOLOGICAL RESPONSES WERE STUDIED BY A COMPUTERIZED CLUSTER ANALYSIS TECHNIQUE WHICH WAS EXTENDED TO DURABILITY RESPONSES USING THE THIN FILM OVEN TEST AND A SPECIAL WEATHEROMETER TEST. THE CLUSTER TECHNIQUE ENALBES CLASSIFICATION OF ASPHALTS IN GROUPS WITH SIMILAR RESPONSES. OTHER CONTRIBUTIONS WERE: (1) CREEP TEST DATA ON ASPHALTS AT LOW TEMPERATURES FOR EVALUATION OF VISCOELASTIC BEHAVIOR, AND THE PRELIMINARY DEVELOPMENT OF A COMPRESSION TEST RHEOLOGICAL TESTS OVER A WIDE RANGE OF TEMPERATURES; (2) COMPARATIVE DATA OF RHEOLOGICAL RESPONSES IN THE SLIDING PLATE, CONE-AND-PLATE, AND EXTRUSION RHEOMETER PROVIDING INFORMATION ABOUT THE RELATIVE MERITS OF THESE INSTRUMENTS WHICH DEFORM ASPHALT IN DIFFERENT GEOMETRIES; (3) NEW PROCEDURE FOR COMPOSITIONAL ANALYSIS AND CHEMICAL EVALUATION OF COMPONENTS; (4) WEATHEROMETER PROCEDURE FOR USE IN THE THIN FILM OVEN TEST FOR ASPHALT RESPONSE TO A DURABILITY TEST ENVIRONMENT. /AUTHOR/
