The vendor denied adding PPA, however decreased to expose what had been added to the binder. When pushed by the department of transport, the supplier disclosed that it was including 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 chemists initially identified.


"No person recognized this product was being included to asphalt, had seen any type of research study on exactly how this could affect performance of hot-mix asphalt pavements, or knew for the length of time and exactly how commonly it was being utilized throughout the nation," states Mueller. After discussions at the technical meeting, he states, "It promptly went from being simply a problem in Illinois to becoming a national and worldwide issue." Part of the goal of the Chemistry Laboratory at TFHRC is to create brand-new examination approaches.

A maker called a dynamic shear rheometer (DSR) was introduced to the industry during the Strategic Freeway Study Program's study task, which ran from 1987 to 1992. The DSR is currently the sector requirement for measuring the viscoelastic residential or commercial properties of paving asphalt. However, the machine was not developed for the paving industry.


For instance, the DSR makes it possible for product developers to develop toothpaste with the appropriate uniformity to make sure that it can be pressed from a tube but not fall off the toothbrush. The DSR tests binder put in between 2 parallel plates about the size of a quarter. One of the plates actions and the equipment determines the viscoelastic residential or commercial properties of the asphalt.
