It has been made use of in leading for more than a hundred years.


Today, however, it is an extremely traded asset that requires premium costs. These costs have actually raised substantially. In 2002, asphalt cost approximately $160 per ton. By the end of 2006, the cost had actually increased to approximately $320 per load, and after that it nearly increased again in 2012 to approximately $610 per ton.

When pressed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what division drug stores at first recognized.


"Nobody knew this product was being contributed to asphalt, had actually seen any kind of research on how this could affect efficiency of hot-mix asphalt sidewalks, or knew for the length of time and exactly how widely it was being used throughout the country," states Mueller. After conversations at the technical conference, he claims, "It rapidly went from being simply an issue in Illinois to becoming a national and global concern."
