It covers a general discussion of polymer chemistry and terns typically used by polymer suppliers; asphalt cement chemistry; typical test methods historically used to evaluate modified asphalts; reported results; comparisons of polymer rnodified asphalt cements and mixtures; proposed binder specifications; and a summary of field trials reported in the literature. Based on this information, the report suggests several experimental designs for use in the completion of the laboratory and field trial phases of this project.enPolymersAsphalt cementsReport
