Abstract: The objectives of this project are: (1) To compare the environmental benefits of Full Depth Reclamation (FDR) mixes with a conventional asphalt emulsion, foamed asphalt, and High Yield Emulsion (HYE), through laboratory testing, analysis of data, and evaluate the durability of optimized HYE mix with accelerated loading and testing; (2) To evaluate the use of recycled concrete aggregate fines (fRCA) as a co-additive with cement stabilizer to treat problematic subgrade soils such as expansive soils through engineering, mineralogical, and chemical testing and embodied carbon analysis.
