The vendor rejected including PPA, yet declined to disclose what had actually been added to the binder. When pressed by the division of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what department chemists originally recognized.


"Nobody recognized this product was being contributed to asphalt, had actually seen any kind of study on just how this could influence performance of hot-mix asphalt sidewalks, or understood for just how lengthy and just how commonly it was being made use of throughout the nation," states Mueller. After discussions at the technological meeting, he states, "It promptly went from being simply an issue in Illinois to coming to be a nationwide and international concern." Component of the mission of the Chemistry Lab at TFHRC is to establish new test methods.

A maker called a dynamic shear rheometer (DSR) was presented to the industry during the Strategic Freeway Research study Program's research study project, which ran from 1987 to 1992. The DSR is currently the sector requirement for determining the viscoelastic homes of leading asphalt. The device was not established for the paving sector (https://on.soundcloud.com/zC6fEriMVi1B9q7z8).


The DSR makes it possible for product developers to develop toothpaste with the ideal uniformity so that it can be squeezed from a tube however not drop off the tooth brush. The DSR tests binder positioned between two identical plates about the dimension of a quarter. One of home plates steps and the machine gauges the viscoelastic properties of the asphalt.
