Project Summary: The existence of Yazoo clay soil in Mississippi frequently causes distress to the pavement and cause deformation at the slopes in highways and levees, which are a critical component in maritime and multimodal transportation infrastructure. Also, the infiltration of the rainwater in the highway and levee slopes leads to landslides, which requires millions of dollars of maintenance each year. Permeability of soil is an important parameter to calculate the water intrusion in geo-infrastructure. A limited study is available on the change in permeability of Yazoo clay soil.

To investigate the change in unsaturated vertical and horizontal permebility and its effect on the maritime and multimodel infrastructures. Especially on the pavement and slopes of highway embankment and levees. 

The project helped to determine the crucial design parameters such as time dependent permeability that was missing for Yazoo clay.
