The vendor denied including PPA, however declined to reveal what had actually been included to the binder. When pressed by the division of transportation, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department drug stores at first identified.


"No person understood this material was being included in asphalt, had seen any kind of study on how this could impact performance of hot-mix asphalt sidewalks, or knew for for how long and how extensively it was being used throughout the nation," says Mueller.

An equipment called a dynamic shear rheometer (DSR) was presented to the sector throughout the Strategic Highway Research Program's research project, which ranged from 1987 to 1992. The DSR is currently the market standard for gauging the viscoelastic homes of paving asphalt. The device was not developed for the paving sector (https://www.indiegogo.com/individuals/37631252).


The DSR makes it possible for product programmers to create tooth paste with the best consistency so that it can be pressed from a tube yet not fall off the toothbrush. The DSR tests binder placed in between two identical plates regarding the size of a quarter. One of home plates relocations and the machine gauges the viscoelastic buildings of the asphalt.
