The vendor rejected adding PPA, however declined to disclose what Continued had actually been included to the binder. When pressed by the department of transport, the supplier disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB contains a small amount of phosphorus, which is what division drug stores at first determined.


"No one understood this material was being added to asphalt, had seen any kind of research on just how this may impact performance of hot-mix asphalt pavements, or knew for for how long and just how extensively it was being utilized throughout the nation," states Mueller.

The machine was not established for the paving industry (https://www.dreamstime.com/a1asphaltsealng_info).


The DSR allows item designers to develop tooth paste with the ideal consistency so that it can be squeezed from a tube however not fall off the toothbrush.
