The sensitivity of SST test to asphalt binder type in the various test track sections was analyzed. The relationship between RSCH test results and field rut depth was poor. This was partly due to the good quality of the track construction, thick pavement structure, and mild summers during the...

It was also found that both CA protocols yielded a more severe level of oxidative aging than 4 years of field aging (using the top 25 to 38mm) on the NCAT Test Track. Finally, virtually all the binder and mixture properties evaluated in the study indicated that the two mixes containing ...

The sections do not show any cracking, suggesting the sections are well-built and a long life is possible. The rutting in the test track is also predicted. All the predicted rut depths are 2-4 mm higher than measured in the field, but the overall ranking of different pavement sections ...
