Abstract

Asphalt cores were sampled from four sites along a major route in Tanzania, where asphalt surfacing was constructed approximately one year ago. The bituminous binder was recovered from cores taken from the wheel path as well as from cores taken from the shoulder, in order to assess whether the action of vehicular trafficking had any effect on the rheological properties of the recovered binders. A range of rheological tests were conducted on the recovered binder, including empirical tests such as penetration and softening point, as well as more fundamental tests such as the G*/sin? and the multi-stress creep recovery test.
