The vendor denied adding PPA, yet decreased to disclose what had actually been contributed to the binder. When pushed by the division of transport, the supplier revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).

Nonetheless, the equipment was not developed for the paving industry.


The DSR makes it possible for item programmers to create tooth paste with the right uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR examinations binder put between two identical plates regarding the size of a quarter. One of the plates actions and the device determines the viscoelastic properties of the asphalt.
