At a degree of 3.5 percent REOB, the variation in the physical examination methods was above the effect of REOB. Actually, it was tough for researchers to analyze whether REOB existed.

One binder specification thought about is the difference between the low temperature level crucial specification temperature for stiffness (S) in the bending light beam rheometer and the flexing light beam rheometer creep incline (m-value) noted as Tcritical. TC = TC (S) TC (m-value). Assessment of this specification is still continuous. Two independent study groups, one from AASHTO and the various other from the Asphalt Institute, wrapped up that more research is required on the usage of REOB in asphalt.


Previously, all asphalt testing gauged engineering residential or commercial properties such as rigidity. These tests do not reveal what materials had actually been added to the asphalt.
