REOB consists of a percentage of phosphorus, which is what division drug stores at first identified.


"No person recognized this material was being added to asphalt, had seen any type of study on exactly how this may impact efficiency of hot-mix asphalt sidewalks, or knew for the length of time and exactly how widely it was being made use of throughout the country," says Mueller.

The device was not developed for the paving sector (https://linktr.ee/a1asphaltseal).


As an example, the DSR allows item designers to create tooth paste with the appropriate uniformity to ensure that it can be squeezed from a tube yet not drop off the tooth brush.
