RAP already has asphalt, albeit aged material that does not have the exact same residential properties of fresh asphalt.

The supplier rejected adding PPA, but declined to reveal what had actually been included to the binder. When pressed by the department of transport, the vendor exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what department chemists initially determined.

"Nobody knew this material was being contributed to asphalt, had actually seen any type of research on how this may affect efficiency of hot-mix asphalt pavements, or recognized for for how long and exactly how commonly it was being utilized throughout the nation," states Mueller. After discussions at the Read Full Article technological conference, he says, "It promptly went from being just a problem in Illinois to becoming a national and global issue."
