EMPLOYING PAVING ASPHALT TEMPERATURE SUSCEPTIBILITY IN THE STRUCTURAL DESIGN OF ASPHALT PAVEMENTS. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

Paving asphalt temperature susceptibility is defined, and a simple method for its measurement is described. The influence of paving asphalt temperature susceptibility on pavement design and performance in hot countries without frost, and in cold climates with frost is described. Requirements for paving asphalt temperature susceptibility that can be added to or incorporated into a paving asphalt specification are proposed and discussed. It is shown that by the addition of suitable polymers, the temperature susceptbilities of paving asphalts can be changed dramatically. This development implies that what has always been an asphalt supplier's market could be changed to an asphalt user's market. In an Appendix, the validity of pen-vis number (PVN) as a measure of paving asphalt temperature susceptibility is examined, together with some of its implications for pavement design and pavement performance.
