The vendor rejected including PPA, however decreased to expose what had actually been included to the binder. When pushed by the department of transport, the supplier revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB).

"No person recognized this product was being contributed to asphalt, had actually seen any kind of study on how this may impact performance of hot-mix asphalt sidewalks, or understood for how lengthy and just how commonly it was being utilized throughout the country," claims Mueller.

The DSR is currently the sector standard for measuring the viscoelastic properties of paving asphalt. Nevertheless, the equipment was not established for the paving market.


For instance, the DSR makes it possible for product designers to develop toothpaste with the right uniformity so that it can be pressed from a tube but not diminish the tooth brush. The DSR tests binder put between two parallel plates concerning the size of a quarter. One of the plates moves and the maker determines the viscoelastic residential or commercial properties of the asphalt.
