The vendor refuted including PPA, yet declined to disclose what had been contributed to the binder. When pushed by the division of transportation, the vendor exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what department drug stores at first determined.


"No one recognized this product was being included in asphalt, had actually seen any kind of study on just how this could influence efficiency of hot-mix asphalt pavements, or understood for how long and how widely it was being utilized throughout the nation," claims Mueller.

The maker was not established for the paving market (https://slides.com/a1asphaltseal).


As an example, the DSR enables product developers to create toothpaste with the best consistency to ensure that it can be pressed from a tube however not diminish the tooth brush.
