The vendor refuted including PPA, however declined to expose what had been included in the binder. When pushed by the department of transport, the vendor disclosed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB consists of a percentage of phosphorus, which is what division drug stores initially identified.


"No one understood this material was being included in asphalt, had seen any research study on exactly how this could influence performance of hot-mix asphalt pavements, or understood for how long and just how extensively it was being used throughout the nation," claims Mueller.

For instance, the DSR makes it possible for product programmers to produce toothpaste with the ideal consistency to make sure that it can be squeezed from a tube however not diminish the toothbrush. The DSR examinations binder put between 2 identical plates about the size of a quarter.
