Research into collapse settlement in compacted soils is described, with special reference to recent cases in Southern Africa where collapse settlement occurred in road embankments following wetting of the soil. The laboratory work described consisted largely of oedometer tests over a range of saturations, on soils from four of these road embankments, compacted in a mould especially designed for this purpose.
