This report develops procedures and associated criteria for laboratory conditioning of asphalt mixtures to simulate short-term aging. The report presents proposed changes to the American Association of State Highway and Transportation Officials (AASHTO) R 30, Mixture Conditioning of Hot-Mix Asphalt (HMA), and a proposed AASHTO practice for conducting plant aging studies. The report will be of immediate interest to materials engineers in state highway agencies and the construction industry with responsibility for design and production of hot and warm mix asphalt.
This synthesis documents the performance tests used in conjunction with volumetric properties for mixtures.
The approach suggested by Ghuzlan and Carpenter (34) considers that only a portion of the dissipated energy is ... RDECa = the average ratio of dissipated energy change at cycle a, comparing to next cycle b; a, b = load cycle a and ...
