A Study of Intermediate Geomaterials and Highly Erodible Rock

There has been substantial research on soil erodibility the past few years at the federal level (e.g., NCHRP 915) and state (e.g., KSU 15-4; KSU 18-5). But there is extremely limited information regarding the erosion characteristics of rock or intermediate geomaterials, such as shale. When these geomaterials are exposed on backslopes or natural slopes under Kansas Department of Transportation (KDOT) management there is the potential for erosion. Determining the geomaterial erodibility will help to estimate the potential material transport over time and whether more stringent erosion control measures are needed. There is significant need to be able to predict the erodibility of these materials. KDOT has had issues with not being able to control shale erosion in ditch backslopes which resulted in Environmental Protection Agency (EPA) fines. There are likely many factors that contribute to the erodibility of rock. This research will measure erosion characteristics of different sediments across Kansas to allow KDOT to identify where more erosion is anticipated.
