A binder with a rating of 64E-22 means the performance of the binder is extended (E) on the
high end. (T/F) - ANSWERS-False
Elastomers are thermoplastic in that changes in temperature affect which characteristics of the
polymer are predominant at any given time, and those changes are recoverable (reversible).
(T/F) - ANSWERS-True
