Project Summary: The existence of Yazoo clay in Mississippi frequently causes distress in Levee and highway embankment slopes, which are an integral component of maritime and multimodal transportation infrastructure. The Vetiver grass provides root depth up to 10 ft., has been utilized to repair slope failures in many Asian countries and can be an excellent and cost-effective bio-engineered solution to repair shallow slides on the expansive soil in the US. The current proposal is focused to investigate the effect of the vetiver grassroots to stabilize levee slopes at the maritime and multimodal transportation infrastructures at Mississippi. The study will help to improve the bio-inspired slope repair technique which will help to mitigate the recurring shallow slopes failures in expansive soil which is common in many miles of maritime and multimodal transportation infrastructure such as levees and highway embankment in Mississippi.
