Short- and long-term aging procedures were developed at Oregon State University under the Strategic Highway Research Program (SHRP) A-003A project. Several alternative methods for short- and long-term aging of asphalt-aggregate were examined. These were subjected to extensive laboratory and field validation test programs. Laboratory validation was done with an extensive testing program using 8 asphalts and 4 aggregates. Field validation utilized 20 test sites and compared the modulus of field aged and laboratory aged specimens.
