Developing Embankment and Subgrade Stabilization Regional Specifications

Currently, the Arkansas State Highway and Transportation Department (AHTD) does not have a standard specification or (set of) guidelines for embankment and subgrade stabilization on statewide or regional level. This project would consider the stabilization of subgrades and embankments up to ten feet in height based on geological regions. Stabilization methods to be considered include, but are not limited to: undercut and backfill, select material, geotextiles, cement stabilization and lime stabilization. Along with establishing guidelines for stabilization, this project would also establish testing protocols for preliminary design and construction.
