Dynamic Shear Rheometers have the capability of measuring an asphalt binders mechanical properties, such as modulus (stiffness), viscosity (slow or resistance to flow) and elasticity (ability to recover when deformed) at whatever temperature and traffic loading a roadway is subjected to.
The Superpave Shear Tester (SST) was developed as part of SHRP research to be one of the HMA mixture performance testers for Superpave mix design. Although it is quite versatile and reasonably able to predict HMA pavement permanent deformation, it has not been widely adopted because of its complexity and cost.
