Project Abstract:
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.
