The supplier rejected including PPA, but decreased to expose what had been contributed to the binder. When pressed by the department of transportation, the supplier revealed that it was including what it called an asphalt extendernow known 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 to asphalt, had actually seen any type of research study on just how this could impact efficiency of hot-mix asphalt pavements, or knew for for how long and how extensively it was being made use of throughout the nation," says Mueller.

A machine called a vibrant shear rheometer (DSR) was introduced to the market throughout the Strategic Freeway Study Program's research study project, which ran from 1987 to 1992.

The DSR allows product programmers to produce tooth paste with the appropriate consistency so that it can be pressed from a tube however not fall off the toothbrush. The DSR examinations binder positioned between two parallel plates regarding the size of a quarter. One of the plates relocations and the machine determines the viscoelastic residential or commercial properties of the asphalt.
