The vendor denied adding PPA, but decreased to disclose what had actually been included in the binder. When pushed 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 originally recognized.


"No one knew this product was being included in asphalt, had actually seen any type of study on exactly how this might impact performance of hot-mix asphalt sidewalks, or understood for for how long and exactly how widely it was being used throughout the nation," claims Mueller.

The machine was not created for the paving market (https://giphy.com/channel/a1aspha1tseal).


For instance, the DSR makes it possible for item designers to produce toothpaste with the appropriate uniformity so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR tests binder placed in between 2 parallel plates concerning the size of a quarter. One of home plates relocations and the device gauges the viscoelastic properties of the asphalt.
