The vendor refuted adding PPA, however declined to disclose what had been included in the binder. When pressed by the division of transport, the vendor revealed 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 originally determined.


"No one understood this product was being included to asphalt, had actually seen any kind of research study on exactly how this may impact efficiency of hot-mix asphalt sidewalks, or understood for the length of time and just how extensively it was being utilized throughout the nation," claims Mueller. After conversations at the technological meeting, he claims, "It swiftly went from being just a problem in Illinois to becoming a national and worldwide worry." Part of the goal of the Chemistry Research Laboratory at TFHRC is to establish new examination methods.

The DSR makes it possible for product designers to create toothpaste with the right consistency so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR examinations binder placed in between two parallel plates concerning the size of a quarter. Among the plates steps and the device determines the viscoelastic buildings of the asphalt.
