The supplier rejected adding PPA, but declined to disclose what had actually been contributed to the binder. When pressed by the department of transport, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists initially recognized.


"No person understood this material was being contributed to asphalt, had actually seen any type of research on how this could impact performance of hot-mix asphalt sidewalks, or understood for how much time and exactly how commonly it was being used throughout the country," claims Mueller. After conversations at the technical meeting, he says, "It promptly went from being just an issue in Illinois to coming to be a nationwide and international problem."

A maker called a vibrant shear rheometer (DSR) was presented to the market during the Strategic Highway Research Program's study task, which ranged from 1987 to 1992.

The machine was not developed for the paving industry (https://canvas.instructure.com/eportfolios/2864493/Home/A1_Professional_Asphalt_Repairs_Paving_Excellence_in_St_Louis).


As an example, the DSR allows item designers to produce toothpaste with the right uniformity to make sure that it can be squeezed from a tube but not drop off imp source the tooth brush.

One of home plates steps and the maker measures the viscoelastic residential properties of the asphalt.
