Project 2.09: Carbonating Subgrate Materials For In Situ Soil Stabilization
Carbonating Subgrade Materials for In Situ Soil Stabilization
Project 2.9
Project Summary
Ground improvement is the in situ alteration of the ground’s material properties, with the ultimate goal of strengthening, stiffening, and/or altering drainage characteristics to benefit design, construction, and performance of civil infrastructure. Carbonation is a process by which carbon dioxide (CO2) gas reacts with alkali minerals naturally occurring and/or introduced in the ground to generate a binder (stable carbonate minerals). The objective of this research project is develop a means to carbonate soil supporting new and existing infrastructure and increase the durability and lifespan of New England’s transportation assets, including roadways susceptible to creep, frost-action, and other modes of deformation that lead to pavement distress.
