"Nobody understood this product was being included to asphalt, had seen any research on how this might influence performance of hot-mix asphalt pavements, or recognized for just how long and just how commonly it was being made use of throughout the nation," claims Mueller.

The device was not developed for the paving industry (https://www.easel.ly/browserEasel/14465169).
