The supplier denied adding PPA, but decreased to reveal what had actually been added to the binder. When pushed by the department of transportation, the supplier revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department drug stores initially recognized.


"Nobody knew this product was being included in asphalt, had actually seen any kind of research on how this may impact performance of hot-mix asphalt pavements, or recognized for for how long and how extensively it was being used throughout the nation," says Mueller. After conversations at the technical meeting, he claims, "It quickly went from being simply a problem in Illinois to coming to be a national and global problem."

The maker was not created for the paving sector (https://www.anyflip.com/homepage/wmzvi#About).


The DSR allows item designers to create tooth paste with the appropriate consistency so that it can be squeezed from a tube but not drop off the tooth brush.
