Use of Recycled Materials in Highway Construction. Appendix I, Database of Recyled Materials Suppliers and Vendors

Description: The major objectives of this study were to examine: (1) the types of recycled materials that are appropriate and feasible as alternative paving materials such as glass and tires; and (2) the types of recycled materials, such as mixed-plastics and compost, that can be utilized in all types of transportation applications other than pavements.

Seven key products are investigated: tires; glass; asphalt concrete; fly ash; compost; mixed plastics; and sign stock. Performance and cost data for pavements is documented for both in-state and nationwide applications. The national experience with the use of waste glass as an additive to asphalt concrete and its use in unbound base material is so highlighted.
Programs for experimental use of recycled material are outlined. Recommendations for staffing and program changes to deal with recycling are also discussed.
