RESEARCH ON ASPHALTIC MATERIALS

SUMMARIES OF REPORTS SUBMITTED DURING THE COURSE OF A 6-YEAR LABORATORY STUDY OF SELECTED ASPHALT CEMENTS ARE PRESENTED. ALSO 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. THIS ANALYSIS WAS EXTENDED TO DURABILITY RESPONSES USING THE THIN FILM OVEN TEST AND A SPECIAL WEATHEROMETER TEST. THE CLUSTER TECHNIQUE ENABLES CLASSIFICATION OF ASPHALTS IN GROUPS WITH SIMILAR RESPONSES. IDENTIFICATION OF THESE GROUPS WITH LEVELS OF PERFORMANCE COULD BE OF VALUE FOR SPECIFICATION PURPOSES. /AUTHOR/
