The supplier refuted including PPA, but declined to reveal what had been contributed to the binder. When pressed by the department of transport, the supplier exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department chemists initially identified.


"No one knew this material was being included to asphalt, had seen any type of study on how this may influence efficiency of hot-mix asphalt pavements, or understood for the length of time and just how commonly it was being made use of throughout the country," states Mueller.

For example, the DSR allows product programmers to create tooth paste with the appropriate consistency to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR examinations binder positioned in between 2 parallel plates regarding the size of a quarter.
