Abstract:
The performance of projects incorporating asphalt-rubber binders has been inconsistent. Thus, a method was needed to provide an understanding of binder physical properties associated with the desirable performance and to quantify them for specification purposes. It was proposed to use the capabilities of a dynamic shear rheometer for comparing the asphalt-rubber binder properties with project performance data to determine the potential for rheological specifications on job samples of the binder. Representative binders from six dense-graded and gap-graded hot mix projects were analyzed.
