The supplier refuted including PPA, however declined to expose what had actually been contributed to the binder. When pressed by the division of transportation, the supplier disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a tiny quantity of phosphorus, which is what division chemists initially recognized.


"No one recognized this material was being contributed to asphalt, had actually seen any study on just how this may impact efficiency of hot-mix asphalt sidewalks, or knew for the length of time and just how extensively it was being utilized throughout the nation," says Mueller. After conversations at the technological meeting, he claims, "It quickly went from being just a problem in Illinois to coming to be a national and worldwide concern."

The equipment was not developed for the paving industry (https://moz.com/community/q/user/a1asphaltseal).


The DSR enables item developers to develop toothpaste with the ideal consistency so that it can be squeezed from a tube but not fall off the tooth brush.
