The California Department of Transportation (CalTrans) joined TPF-5(2130 as a state partner in 2010. Caltrans has no experience using recycled asphalt shingles (RAS) in asphalt applications and is currently working with Iowa State University (ISU) to develop a draft RAS specification for both post-manufactured and post-consumer RAS.
CalTrans will be hosting two shingle recycling workshops in 2011 to bring interested partners from the public and private sector to discuss quality control protocols for achieving a quality RAS end product. Discussions on potential demonstration projects will also be discussed.
CalTrans is currently reviewing their goals and key outcomes for their demonstration project to be identified and scheduled for the 2012 construction season.
