The supplier refuted including PPA, yet declined to expose what had been contributed to the binder. When pushed by the department of transportation, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department drug stores at first determined.


"No one recognized this product was being added to asphalt, had actually seen any study on just how this may affect efficiency of hot-mix asphalt pavements, or knew for the length of time and how extensively it was being utilized throughout the country," states Mueller.

A maker called a dynamic shear rheometer (DSR) was introduced to the industry during the Strategic Highway Research study Program's study project, which ran from 1987 to 1992.

The device was not created for the paving sector (https://penzu.com/p/6a2868f92af16f91).


The DSR enables item designers to produce toothpaste with the appropriate consistency so that it can be squeezed from a tube yet not fall off the toothbrush. The DSR tests binder placed in between two parallel plates concerning the dimension of a quarter. One of home plates moves and the machine measures the viscoelastic homes of the asphalt.
