EVALUATION OF LOW TEMPERATURE AND PERMANENT DEFORMATION CHARACTERISTICS OF SOME ENGINEERED ASPHALTS. PROCEEDINGS OF THE THIRTY-FOURTH ANNUAL CONFERENCE OF THE CANADIAN TECHNICAL ASPHALT ASSOCIATION, HALIFAX, NOVA SCOTIA, 1989
Research programs conducted at the university of Alberta have involved the evaluation of various types of polymers added to conventional paving grade asphalt cements in order to provide comparative values under high and low temperatures common to western Canada. Observations of laboratory tests have shown that polymer modified mixes generally exhibit higher failure stresses, higher failure strains and lower failure stiffness at low temperatures down to -30c, when compared with conventional asphalt cements. At higher temperatures of up to 45c the polymer modified mixes exhibit considerably less permanent strain. It is expected that these characteristics should enable an asphalt concrete pavement with a polymer modified binder to be more resistant to thermally induced stresses at low temperatures and permanent deformation due to traffic loading at high service temperatures.
