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


Today, nevertheless, it is a highly traded product that demands premium prices. These rates have actually raised drastically. In 2002, asphalt cost approximately $160 per load. By the end of 2006, the expense had doubled to roughly $320 per heap, and after that it practically doubled once more in 2012 to around $610 per ton.
