The vendor refuted including PPA, however declined to reveal what had been contributed to the binder. When pressed by the department of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department drug stores originally determined.


"Nobody knew this product was being included to asphalt, had seen any type of research study on exactly how this may influence performance of hot-mix asphalt sidewalks, or understood for the length of time and exactly how extensively it was being used throughout the country," claims Mueller.

For instance, the DSR allows product designers to produce tooth paste with the ideal uniformity to make sure that it can be squeezed from a tube yet not diminish the toothbrush. The DSR tests binder put in between two identical plates regarding the size of a quarter. Among the plates moves and the equipment determines the viscoelastic properties of the asphalt.
