observed with the two crumb rubber modifiers. Except for crumb rubber type polymer modifiers, the general agreement among the three rut rankings indicate the potential for using the APA to predict the relative rutting performance of polymer modifiers. Considering the True PG Grade and Manual Rut Measurements rankings in table 8 there appears to be a poor correspondence between these two rankings. Note that both of the crumb rubber modifiers and the Kraton modifier are within 4 rankings relative to each other. This observation suggests that the selection of a modified asphalt binder grade based on the high temperature component of the PG designation could be quite inappropriate for a given project, especially when crumb rubber modifiers are considered for use in the HMA. 28
