Abstract

Road projects may require constructing culverts to divert water under or alongside a road. Earth pressure on buried concrete culverts varies depending on the depth of the culvert and the amount of fill dirt placed on top of it. As soil characteristics and properties vary across states, national design values may not reflect Iowa conditions. Iowa DOT monitored two culverts from construction through operation to learn how earth pressure changes over time. The results support the agency’s interest in surveying other culverts in the state.
