...The development of the Strategic Highway Research Program (SHRP) asphalt binder criterion for low-temperature cracking was based on the assumption that the 2-h mixture stiffness correlated well with the severity of thermal cracking in the field (1)....

...To expedite the testing process, the time–temperature superposition principle was used to show that, for asphalt binders in general, the stiffness at 60 s at temperature T1°C is approximately equal to the stiffness at 2 h at temperature T1−10°C (1)....
