When pushed by the division of transportation, the vendor disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a little quantity of phosphorus, which is what division chemists at first identified.


"Nobody understood this product was being contributed to asphalt, had seen any research study on how this could impact efficiency of hot-mix asphalt pavements, or recognized for how much time and how extensively it was being used throughout the nation," states Mueller.

The machine was not established for the paving sector (https://padlet.com/a1asphaltsealng/my-stellar-padlet-8k4iv5oxbxezxc6c).


The DSR enables product programmers to create toothpaste with the right consistency so that it can be pressed from a tube however not fall off the toothbrush.
