REOB includes a little quantity of phosphorus, which is what department chemists at first identified.


"No one understood this material was being included in asphalt, had actually seen any kind of study on exactly how this may affect performance of hot-mix asphalt pavements, or understood for the length of time and how extensively it was being utilized throughout the country," claims Mueller.
