The vendor refuted adding PPA, but decreased to reveal what had been contributed to the binder. When pressed by the department 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 includes a percentage of phosphorus, which is what division chemists originally determined.


"No person knew this material was being included in asphalt, had seen any kind of study on just how this could affect performance of hot-mix asphalt pavements, or understood for just how lengthy and how commonly it was being utilized throughout the country," states Mueller.

A machine called a vibrant shear rheometer (DSR) was introduced to the market throughout the Strategic Highway Research study Program's research task, which ran from 1987 to 1992. The DSR is now the sector standard for determining the viscoelastic properties of paving asphalt. The machine was not created for the paving industry (http://go.bubbl.us/e16bb8/19e3?/New-Mind-Map).


The DSR allows item designers to develop toothpaste with the appropriate uniformity so that it can be squeezed from a tube but not fall off the tooth brush.
