Freeway construction in Melbourne often involves deep cuts in unfavourably jointed Silurian mudstones. Steel dowels have been successfully used to quickly and economically stabilise potential failures in these conditions. During the construction of the Eastern Freeway two significant rock slides occurred and several other potential slides were evident. The jointing system was assessed and the mode of failure determined. A system of steel dowels was then installed, decreasing the probability of these slides occurring. The use of a similar dowelling system is intended to stabilise a proposed railway cut, associated with the construction of the Greensborough Freeway, where similar conditions exist to those above. This represents an estimated saving of about 90 percent of the cost of a conventional retaining wall solution. /Author/TRRL/
