The vendor rejected adding PPA, but decreased to expose what had been included to the binder. When pressed by the division of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department chemists at first identified.

"No person knew this product was being added to asphalt, had seen any kind of research on how this could affect efficiency of hot-mix asphalt pavements, or knew More about the author for the length of time and exactly how widely it was being used throughout the country," says Mueller. After discussions at the technical meeting, he states, "It quickly went from being simply a concern in Illinois to becoming a nationwide and global problem."

A device called a dynamic shear rheometer (DSR) was presented to the industry during the Strategic Freeway Research Program's study project, which ranged from 1987 to 1992. The DSR is now the industry standard for gauging the viscoelastic homes of paving asphalt. The machine was not developed for the paving industry (https://packersmovers.activeboard.com/t67151553/how-to-connect-canon-mg3620-printer-to-computer/?ts=1713554746&direction=prev&page=last#lastPostAnchor).

The DSR enables item developers to create tooth paste with the ideal uniformity so that it can be squeezed from a tube however not fall off the tooth brush. The DSR tests binder positioned between 2 parallel plates concerning the dimension of a quarter. Among the plates steps and the machine determines the viscoelastic residential or commercial properties of the asphalt.
