The supplier refuted adding PPA, however decreased to expose what had been included in the binder. When pressed by the division of transportation, the supplier disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB contains a percentage of phosphorus, which is what division drug stores at first recognized.


"No person knew this material was being included in asphalt, had actually seen any kind of research on how this might influence efficiency of hot-mix asphalt pavements, or knew for how long and exactly how extensively it was being used throughout the country," says Mueller. After discussions at the technical meeting, he states, "It rapidly went from being just a problem in Illinois to coming to be a nationwide and worldwide problem." Part of the objective of the Chemistry Laboratory at TFHRC is to develop new examination methods.

As an example, the DSR enables product developers to create tooth about his paste with the appropriate uniformity to ensure that it can be squeezed from a tube yet not drop off the tooth brush. The DSR examinations binder placed between 2 parallel plates regarding the size of a quarter. Among home plates moves and the maker measures the viscoelastic buildings of the asphalt.
