Performance, Binder Properties  
Key Words:
asphalt-rubber binder, asphalt-rubber hot mix, rheology of asphalt-rubber binders  
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.
