The vendor refuted including PPA, but declined to reveal what had been included in the binder. When pressed by the department of transport, the supplier revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB).

"Nobody understood this product was being contributed to asphalt, had actually seen any kind of study on exactly how this could impact performance of hot-mix asphalt sidewalks, or understood for how much time and just how commonly it was being used throughout the country," says Mueller.

The DSR enables item developers to create toothpaste with the right uniformity so that it can be squeezed from a tube but not drop off the tooth brush. The DSR examinations binder placed in between 2 identical plates concerning the dimension of a quarter. Among home plates relocations and the device measures the viscoelastic properties of the asphalt.
