Full Depth Reclamation in Maintenance Operations Using Emerging Technologies

As documented in the initial Project 0-6271, full depth recycling (FDR) is the main approach used all over Texas to rehabilitate thin roadways that are structurally damaged. In the FDR process, the existing surface and base materials are pulverized and mixed together and treated with a stabilizer. The type and amount of stabilizer to add is designed in the laboratory to provide sufficient strength and moisture resistance. The compacted treated base then receives a thin surfacing. This project shall identify and use these emerging FDR technologies in maintenance operations of districts to design and construct experimental sections with a range of new stabilizers, most notably cement slurries, foamed asphalt, and engineered emulsions. These sections shall typically be short distressed high profile roadways in Texas Department of Transportation (TxDOT) districts in which the research team can work with the TxDOT district lab and construction personnel to design, construct, and monitor the experimental FDR sections with these emerging technologies. Guidelines for using these emerging FDR technologies in maintenance operations shall also be developed.
