The supplier refuted including PPA, however declined to disclose what had actually been included to the binder. When pressed by the department of transportation, the vendor revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department chemists originally determined.


"Nobody knew this product was being included to asphalt, had seen any study on exactly how this might affect efficiency of hot-mix asphalt pavements, or recognized for for how long and just how commonly it was being used throughout the nation," states Mueller.

Nonetheless, the equipment was not established for the paving market.


As an example, the DSR enables product programmers to develop toothpaste with the right uniformity to make sure that it can be pressed from a tube however not diminish the toothbrush. The DSR examinations binder put between 2 identical plates regarding the size of a quarter. Among home plates steps and the machine measures the viscoelastic properties of the asphalt.
