Project Objective

Utilize field constructed and instrumented slopes to investigate the performance of stabilized and natural slope sections using the agent and agent combinations and treatment percentages in the salty and clayey soils near Haiti, Missouri along the I-55 corridor.

Project Abstract

A laboratory investigation of the efficacy of agents which may be applied to slopes of alluvial silt soils and Sharkey clay soils along the I-55 corridor south of Sikeston, Missouri, to provide economical stability which will prevent slope failures and surface erosion in existing slopes and those of future construction in the area. Soils studied will include two taken from failed slope areas near Haiti, Missouri. Agents to be considered include Quick Lime, Lime Kiln Dust, Portland Cement and Fly Ash.
