A review of international literature covering the use of fibre reinforcement in cohesive and non-cohesive soils as a means of strengthening these materials was begun in 1992. The contribution of fibres to the characteristics of mixtures of soil and fibre is presented and, in particular, the effect of the fibres on the mixture's strength and ductility under both static and dynamic loading is examined.
A range of potential fibre-reinforcing materials is outlined, and the application of them in improving the performance of road pavement materials and in earthworks construction is discussed. Comparative costs for soils stabilised using fibre, lime and cement are also presented. Recommendations for the use of this technique and for future investigations are presented.
