The vendor rejected adding PPA, yet declined to expose what had been included in the binder. When pushed by the department of transport, the vendor exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB has a percentage of phosphorus, which is what department chemists at first recognized.


"No one recognized this material was being added to asphalt, had actually seen any research on just how this could influence performance of hot-mix asphalt sidewalks, or understood for for how long and exactly how commonly it was being used throughout the nation," claims Mueller.

An equipment called a vibrant shear rheometer (DSR) was introduced to the market during the Strategic Freeway Research Program's research study task, which ranged from 1987 to 1992. The DSR is now the sector criterion for measuring the viscoelastic residential or commercial properties of paving asphalt. The device was not developed for the paving market (https://www.indiegogo.com/individuals/37631252).


The DSR makes it possible for product designers to develop tooth paste with the best consistency so that it can be pressed from a tube however not fall off the tooth brush. The DSR tests binder placed in between 2 parallel plates regarding the dimension of a quarter. Among the plates actions and the equipment determines the viscoelastic residential properties of the asphalt.
