The supplier refuted adding PPA, yet decreased to expose what had been added to the binder. When pushed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB has a percentage of phosphorus, which is what division drug stores initially recognized.


"Nobody recognized this material was being added to asphalt, had actually seen any type of research study on how this may affect efficiency of hot-mix asphalt pavements, or understood for the length of time and how extensively it was being made use of throughout the nation," says Mueller. After discussions at the technical meeting, he states, "It promptly went from being simply a problem in Illinois to ending up being a nationwide and global issue." Component of the goal of the Chemistry Lab at TFHRC is to establish brand-new test approaches.


The properties of asphalt binders vary extensively relying on the source of the unrefined oil and the refining procedure made use of.

A maker called a dynamic shear rheometer (DSR) was presented to the industry during the Strategic Freeway Study Program's study project, which ran from 1987 to 1992. The DSR is now the industry standard for gauging the viscoelastic residential or commercial properties of paving asphalt. Nonetheless, the maker was not created for the paving industry.


The DSR allows product designers to produce tooth paste with the appropriate uniformity so that it can be squeezed from a tube however not fall off the tooth brush. The DSR tests binder positioned between 2 parallel plates concerning the size of a quarter. Among the plates relocations and the equipment gauges the viscoelastic residential or commercial properties of the asphalt.
