The construction and improvement of roads on peat lands has always been a challenging taskin geotechnical engineering. Rampart roads, which are a particular feature of the bog roads in Ireland, arecaused by the excavation of peat from the roadsides over many years for use as a domestic fuel. The historicaldevelopment of rampart roads and current performance under the added traffic loading is discussed. Various roadimprovement methods have been applied to improve the road ability to carry traffic and the technical aspectsand performance of the methods are discussed. In particular, the performance of the improvement methods isrelated to the geotechnical properties of the underlying bog foundation.
