Location and Availability of Waste and Recycled Materials in Texas and Evaluationof Their Utilization Potential in Roadbase

摘要

The report summarizes the results of a literature search conducted to determineengineering applications of various waste and recycled materials (WRMs). The results of a material availability and location survey conducted to determine the availability of WRMs within the Texas Department of Transportation (TxDOT) are also presented. Information of interest included the location, type, and quantity of WRMs present. Technical laboratory studies that have been used in the past to evaluate WRMs fail to take into account the socio-economic and environmental benefits of using these materials. To overcome this problem, a WRM evaluation method was developed that considers the socio-economic and environmental benefits in addition to the technical and economic aspects when evaluating WRMs for various engineering applications. An initial screening method was also incorporated to screen out materials having low or no utilization potential. Only those materials showing high potential will be subjected to extensive technical studies.
