The vendor denied adding PPA, but declined to expose what had been contributed to the binder. When pressed by the division of transportation, the vendor exposed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB includes a tiny quantity of phosphorus, which is what department chemists initially identified.

"Nobody understood this material was being included in asphalt, had seen any research study on how this could influence efficiency of hot-mix asphalt pavements, or recognized for the length of time and exactly how extensively it was being utilized throughout the country," claims Mueller. After conversations at the technical conference, he states, "It rapidly went from being simply a concern in Illinois to coming to be a national and international issue." Part of the goal of the Chemistry Laboratory at TFHRC is to create new examination techniques.

The equipment was not created for the paving market (https://www.evernote.com/shard/s452/sh/55e605bb-a7ab-087f-2bbb-4cc3e94c5474/UvHUCPgKcZ18HESRJSnkIId24flOmNta2DAPD8UMVaYOk5-3NsYjse3oCA).

As an example, the DSR makes it possible for product programmers to develop toothpaste with the best consistency to make sure that it can be pressed from a tube however not diminish the tooth brush.
