TRB Webinar: Cold Central Plant Recycling - A Proven Paving Approach Using 100% Recycled Materials (9-2015)
On Thursday, September 3, 2015, TRB held a webinar on cold central plant recycling (CCPR). CCPR is a paving technique that uses 100% recycled materials, which allows contractors to process the recycled asphalt pavement (RAP) material they already have. Traditionally, this technique has not been frequently used in the United States, but recent research illustrates that it may be a viable option for use in higher volume applications. Presentation slides are available through the link.
