"Thesis describes a study to investigate the effect of hardening (aging) on two grade AR-4000 asphalts used in pavements on U.S. Highway 395 north of Reno, Nevada. The change in viscosity as determined using a sliding plate microviscometer was used as an index to hardening. Field and laboratory aging curves were studied."
