The vendor denied adding PPA, however declined to expose what had been added to the binder. When pushed by the division of transport, the supplier revealed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB contains a small amount of phosphorus, which is what division drug stores at first determined.


"No one understood this product was being included in asphalt, had seen any research study on exactly how this could affect performance of hot-mix asphalt pavements, or knew for exactly how long and how extensively it was being made use of throughout the country," says Mueller.

A device called a dynamic shear rheometer (DSR) was introduced to the industry during the Strategic Highway Research study Program's research study task, which ranged from 1987 to 1992. The DSR is now the sector criterion for determining the viscoelastic residential or commercial properties of paving asphalt. However, the machine was not established for the paving market.


The DSR enables item designers to create toothpaste with the right consistency so that it can be pressed from a tube yet not drop off the tooth brush. The DSR tests binder placed between two parallel plates regarding the size of a quarter. One of the plates relocations and the equipment gauges the viscoelastic residential properties of the asphalt.
