Recycled Concrete Aggregate
Federal Highway Administration National Review
Purpose/Objectives:
The purpose of this review is to capture for technical deployment the most advanced uses of recycled concrete aggregate and then transfer the knowledge with all State Transportation Agencies (STA). Through this sharing of information, we intend to showcase how other STAs overcame barriers and advanced the routine use of recycled concrete as aggregate. Specific uses or applications will be identified along with their barriers and benefits to implementation. Specifications, construction practices and implementation challenges will also be documented. This information will then be disseminated to all STAs through technical guidance, training, and guide specifications, as necessary.
Scope:
Minnesota, Utah, Virginia, Texas, and Michigan were the states chosen for an in-depth review of their recycled concrete aggregate program. These states were chosen because of their experience with recycling concrete aggregate. For each state visited, the review team will consist of 5 members. One individual from the leadership team will be present at all reviews to assure consistency. The other members of the review team will include individuals from the Federal Highway Administration (FHWA), Environmental Protection Agency (EPA), American Concrete Institute (ACI), or American Association of State Highway Transportation Officials (AASHTO).
For each state visited, the team will review recycled concrete aggregate applications utilized by that particular state for the purpose of developing a consolidated report at the completion of all the state visits that addresses the objectives listed above. It is intended that the final report be widely circulated to assist other states that may consider utilizing these applications. Additionally, a technology deployment package will be distributed to the FHWA Resource Center for further deployment.
