Greening Highways and Roadways
The buy-recycled provisions in the Resource Conservation and Recovery Act apply both to purchases made by Federal agencies and to purchases made by state and local recipients of Federal funds. In February of 2002, to implement the RCRA provisions, the Federal Highway Administration issued a formal policy on the use of recovered materials in highway applications, http://www.fhwa.dot.gov/legsregs/directives/policy/recmatpolicy.htm. It states, in part: "This recycling policy statement is offered to advance the use of recycled materials in highway applications. It is intended to provide leadership, direction, and technical guidance to the transportation community for the use of recycling technology and materials in the highway environment." It memorializes long-standing FHWA policy of supporting the research and development of highway applications for recovered materials.

As part of supporting the use of recovered materials in highway construction and maintenance, FHWA and the University of New Hampshire formed the Recycled Materials Resource Center, http://www.rmrc.unh.edu/. The Center provides research and informational materials, sponsors educational seminars, and serves as a conduit for promoting the beneficial use of recovered materials in highway applications.
