Roadway Recycled Materials Summaries

As part of our Road to Recycling initiative, a road construction industry panel identified 12 materials with great potential in road construction that are readily available in Texas in potentially large volumes, offer engineering benefits, cost-effective pricing and no increased environmental risks.

We have assembled packets of information for each of these materials. The packets include a material overview, research summaries, case studies, a list of current specifications, a list of material sources and a summary of experiences with the material.
