The vendor rejected adding PPA, yet declined to disclose what had actually been included in the binder. When pressed by the division of transportation, the vendor revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB has a small quantity of phosphorus, which is what division chemists initially determined.


"No person knew this material was being included to asphalt, had actually seen any study on how this could influence efficiency of hot-mix asphalt pavements, or recognized for for how long and just find more info how widely it was being utilized throughout the country," claims Mueller.

The equipment was not created for the paving industry (https://myanimelist.net/profile/alasphaltseal).


For instance, the DSR makes it possible for item designers to develop toothpaste with the right uniformity to make sure that it can be pressed from a tube however not fall off the tooth brush.
