Experiments with epoxy resin mortar joints were carried out in 1971 at Portsdown Hill between Southampton and Portsmouth on the line of the M27 motorway. The soil consisted of medium-to-hard chalk from ground level down, selected because it was considered that hard driving into the chalk would provide a severe test for the joint. Three different types of joint were tried: four steel dowels cast in the extension section with matching holes in the lower section; a concrete spigot and socket joint similarly arranged, and a plain butt joint. Liquid resin was poured into the joints. The first type of joint was the most successful and is considered a satisfactory construction method.
