Implementation of the waste and reclaimed materials evaluation system. Research report

Large quantities of waste materials are generated in the United States every year. Due to societal and environmental concerns many states have enacted legislation to promote their use in highway construction projects. The standard approach to charcterize these materials has been to evaluate them in technical laboratory studies which is not appropriate because these materials do not match natural aggregate in technical quality and may still have a high societal, environmental and economic value. A Waste and Reclaimed Materials (WRM) evaluation process has already been developed which takes into account such factors. This WRM Evaluation process is carried out before detailed technical and economic studies are done to develop specifications for their use. The determinination of their utilization potential is based on technical, economic, societal and environmental aspects. An initial screening process is also incorporated which is used to discard WRMs which clearly displays a low utilization potential. The Analytic Hierarchy Process (AHP) from decision analysis theory is used to assign weights to the four evaluation sub-systems and the respective attributes based on their importance. Implementation of this systems was carried out after the system was verified by detailed laboratory studies and economic analysis. All the available WRMs were subjectedmore » to this evaluation method and were ranked from the highest utilization potential to the lowest. The selected top three WRMs, reclaimed asphalt, Portland cement concrete pavement, and electric arc furnace slag, were subjected to detailed laboratory and economic analyses to determine their viability and to develop specifications for their use in roadhouse construction. The WRM evaluation process, laboratory studies, and the implementation package are presented in the report.« less
