The supplier denied adding PPA, yet declined to disclose what had actually been included to the binder. When pushed by the division of transportation, the supplier exposed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB consists of a percentage of phosphorus, which is what division chemists at first determined.


"Nobody recognized this product was being included in asphalt, had actually seen any kind of study on exactly how this might affect performance of hot-mix asphalt pavements, or knew for for how long and how extensively it was being used throughout the country," claims Mueller.

The machine was not developed for the paving industry (https://zzri1z2o90l.typeform.com/to/BPqH2MM1).


The DSR allows item designers to develop toothpaste with the best uniformity so that it can be squeezed from a tube however not fall off the tooth brush. The DSR tests binder placed in between 2 identical plates concerning the size of a quarter. One of home plates moves and the device measures the viscoelastic properties of the asphalt.
