RAP currently has asphalt, albeit aged material that does not have the very same properties of fresh asphalt.

The vendor rejected adding PPA, yet decreased to disclose what had actually been included in the binder. When pressed by the department of transport, the supplier disclosed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what division chemists initially determined.


"No one knew this material was being included in asphalt, had actually seen any study on exactly how this may influence performance of hot-mix asphalt sidewalks, or understood for how long and how extensively it was being utilized throughout the country," states Mueller. After discussions at the technological meeting, he claims, "It rapidly went from being just a problem in Illinois to becoming a national and international issue." Part of the goal of the Chemistry Research Laboratory at TFHRC is to develop new examination methods.

A machine called a dynamic shear rheometer (DSR) was presented to the sector during the Strategic Freeway Research Program's study task, which ranged from 1987 to 1992. The DSR is currently the market criterion for determining the viscoelastic homes of paving asphalt. Nonetheless, the device was not developed for the paving market.


For instance, the DSR enables item developers to create toothpaste with the ideal uniformity so that it can be squeezed from a tube yet not diminish the toothbrush. The DSR examinations binder put between two parallel plates about the size of a quarter. One of the plates moves and the machine measures the viscoelastic homes of the asphalt.
