The supplier refuted including PPA, yet decreased to disclose what had been contributed to the binder. When pushed by the department of transportation, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).

The DSR enables item developers to develop tooth paste with the best consistency so that it can be squeezed from a tube but not drop off the tooth brush. The DSR tests binder placed in between 2 identical plates regarding the size of a quarter. One of the plates moves and the equipment determines the viscoelastic residential or commercial properties of the asphalt.
