The vendor rejected including PPA, however decreased to reveal what had been included to the binder. When pushed by the department of transportation, the supplier exposed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what division chemists at first recognized.


"Nobody understood this product was being contributed to asphalt, had seen any research on just how this might impact performance of hot-mix asphalt pavements, or recognized for the length of time and exactly how commonly it was being utilized throughout the country," claims Mueller. After discussions at the technical meeting, he states, "It promptly went from being just a problem in Illinois to becoming a nationwide and worldwide issue."

A machine called a vibrant shear rheometer (DSR) was presented to the market throughout the Strategic Freeway Research Program's research project, which ran from 1987 to 1992. The DSR is now the market requirement for determining the viscoelastic properties of paving asphalt. However, the equipment was not developed for the paving industry.


As an example, the DSR allows product programmers to create toothpaste with the right consistency to ensure that it can be pressed from a tube yet not fall off the toothbrush. The DSR tests binder positioned between two parallel plates about the size of a quarter. Among the plates actions and the equipment gauges the viscoelastic residential properties of the asphalt.
