The objectives of this research were first, to develop a methodology for (1) assessing the suitability and practicability of specific waste and recycled materials (WRMs) in transportation applications, (2) determining appropriate uses, (3) developing design and construction guidelines, and (4) evaluating long-term in-service performance, and second, to apply the methodology to a spectrum of WRMs.

The key product of the project was the NCHRP Waste and Recycled Materials Information Database and companion user's manual. The database is a Windows 95-based program containing information on 21 WRMs identified for use in transportation-related applications.

The WRM database was published on CD-ROM as CRP-CD-5. However, its compatibility with more recent versions of the Windows operating system is unknown.
