The supplier denied adding PPA, yet declined to disclose what had actually been added to the binder. When pressed by the division of transport, the supplier disclosed that it was adding what websites it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB).

For instance, the DSR enables item designers to produce tooth paste with the appropriate uniformity so that it can be squeezed from a tube but not diminish the tooth brush. The DSR examinations binder put in between two parallel plates concerning the dimension of a quarter. One of home plates moves and the maker measures the viscoelastic buildings of the asphalt.
