Download or read book Investigation of the Relationship Between Field Performance and Laboratory Aging Properties of Asphalt Mixtures written by CA. Bell and published by . This book was released on 1995 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
