The vendor denied adding PPA, but declined to expose what had been contributed to the binder. When pressed 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 bases (REOB). REOB has a percentage of phosphorus, which is what division chemists at first identified.


"Nobody knew this material was being contributed to asphalt, had seen any type of research on just how this might affect efficiency of hot-mix asphalt sidewalks, or understood for just how long and just how commonly it was being used throughout the country," says Mueller. After conversations at the technical conference, he claims, "It promptly went from being just a concern in Illinois to becoming a national and international problem." Part of the goal of the Chemistry Laboratory at TFHRC is to develop brand-new examination techniques.

The device was not created for the paving industry (https://www.huntingnet.com/forum/members/a1asphaltseal.html).


For example, the DSR allows product designers to create tooth paste with the appropriate consistency so that it can be pressed from a tube but not diminish the tooth brush. The DSR examinations binder positioned between 2 parallel plates concerning the size of a quarter. One of home plates moves and the machine determines the viscoelastic residential properties of the asphalt.
