The supplier rejected adding PPA, yet declined to expose what had actually been contributed to the binder. When pushed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists originally recognized.


"No one understood this material was being included in asphalt, had actually seen any kind of research study on just how this could go to my blog impact performance of hot-mix asphalt sidewalks, or understood for how much time and just how commonly it was being made use of throughout the country," claims Mueller.
