This fifth report provides guidance on geological investigations, durability classification of shales, design features, and construction procedures unique to compacted shale embankments for highways. Guidance is also given on techniques for evaluating existing shale embankments and remedial treatment methods for distressed shale embankments. Index tests and classification criteria for determining shale durability, techniques for evaluating excavation characteristics, and alternative procedures for excavation, placement and compaction of shales to achieve adequate stability and minimum settlement are described. The use of drainage measures, selective excavation and placement of nondurable shales in thin lifts with procedural compaction provisions based on field test pads is emphasized. /FHWA/
