"No person knew this product was being contributed to asphalt, had actually seen any type of research study on exactly how this might impact performance of hot-mix asphalt pavements, or knew for exactly how lengthy and just how extensively it was being used throughout the nation," says Mueller.

The DSR enables product programmers to produce tooth paste with the appropriate uniformity so that it can be pressed from a tube yet not fall off the toothbrush.
