The supplier refuted including PPA, but declined to reveal what had actually been included to the binder. When pushed by the department of transportation, the supplier disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what department chemists originally recognized.


"No person understood this material was being included in asphalt, had seen any kind of research study on just how this may affect efficiency of hot-mix asphalt sidewalks, or understood for the length of time and how commonly it was being utilized throughout the country," says Mueller.

A machine called a dynamic shear rheometer (DSR) was introduced to the industry throughout the Strategic Freeway Research Program's research task, which ran from 1987 to 1992. The DSR is currently the sector criterion for gauging the viscoelastic properties of leading asphalt. Nonetheless, the equipment was not developed for the paving sector.


The DSR allows product developers to develop tooth paste with the best uniformity so that it can be pressed from a tube however not drop off the toothbrush. The DSR this post tests binder put between 2 identical plates concerning the dimension of a quarter. One of home plates moves and the machine determines the viscoelastic buildings of the asphalt.
