The supplier rejected adding PPA, yet decreased to reveal what had actually been included in the binder. When pushed by the division of transportation, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a small quantity of phosphorus, which is what division drug stores initially identified.


"No one knew this product was being added to asphalt, had actually seen any kind of research study on how this may affect efficiency of hot-mix asphalt pavements, or understood for the length of time and exactly how extensively it was being utilized throughout the nation," states Mueller. After discussions at the technological meeting, he claims, "It swiftly went from being just a concern in Illinois to coming to be a national and global concern."

A machine called a dynamic shear rheometer (DSR) was presented to the industry during the Strategic Freeway Research Program's research study task, which ran from 1987 to 1992. The DSR is currently the industry criterion for measuring the viscoelastic residential properties of paving asphalt. Nevertheless, the equipment was not developed for the paving industry.


For instance, the DSR enables item designers to create toothpaste with the best consistency so that it can be squeezed from a tube yet not diminish the tooth brush. The DSR examinations binder put between 2 identical plates regarding the size of a quarter. Among the plates moves and the machine gauges the viscoelastic residential my link properties of the asphalt.
