CHARACTERISTICS OF ASPHALTS AS RELATED TO THE PERFORMANCE OF FLEXIBLE PAVEMENTS

Pavement cracking and related distress are the major problem with Utah highways. This study was initiated to isolate the causes and propose solutions to this problem. The most significant factor influencing transverse cracking was found to be the source of asphalt crude. This difference in asphalt performance was found to be related to the parameters temperature susceptibility, force ductility, ductility, aging index, chemical composition, and cannon cone viscosity. The viscosity and penetration grading methods were found to be inadequate in controlling pavement cracking. The high level of air voids content was found to cause a more rapid hardening of the asphalt binder than the low level of air voids.
