The vendor rejected adding PPA, yet declined to disclose what had been added to the binder. When pressed by the department of transportation, the vendor exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB).

The DSR allows item programmers to develop tooth paste with the ideal uniformity so that it can be pressed from a tube however not drop off the tooth brush. The DSR examinations binder placed between 2 identical plates concerning the size of a quarter. One of home plates steps and the device measures the viscoelastic homes of the asphalt.
