The vendor denied including PPA, but decreased to reveal what had actually been contributed to the binder. When pushed by the division of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB contains a small quantity of phosphorus, which is what division chemists originally identified.


"No person knew this product was being contributed to asphalt, had actually seen any kind of research study on how this may influence efficiency of hot-mix asphalt sidewalks, or recognized for for how long and how widely it was being utilized throughout the nation," states Mueller.

A maker called a vibrant shear rheometer (DSR) was introduced to the industry during the Strategic Freeway Research Program's research project, which ran from 1987 to 1992. The DSR is currently the market requirement for gauging the viscoelastic properties of paving asphalt. The machine was not developed for the paving sector (https://www.huntingnet.com/forum/members/a1asphaltseal.html).


As an example, the DSR makes it possible for item designers to create tooth paste with the appropriate uniformity to ensure that it can be squeezed from a tube yet not fall off the tooth brush.
