Abstract:

In many parts of the world, high-level engineering solutions are inappropriate for rural areas where expertise, skills, and equipment are unavailable. Often these areas suffer from difficult terrain that also makes accessibility a problem. At the 1999 International Conference on Low-Volume Roads, a design catalogue was presented for a flexible portland cement concrete pavement using geocells, which was suitable for labor-intensive construction. However, the catalogue required layer works, which meant that construction equipment, although minimal, was required. This was seen as a major constraint, particularly when communities become involved in the construction of these local access roads. In addition, in difficult terrain the handling of drainage becomes a major engineering undertaking for which expertise may not be locally available. The aim of this study was to develop a structural design catalogue that caters for the range of traffic and material conditions typically encountered in these remote rural areas. Additionally, standard solutions were developed for dealing with steep gradients and surface drainage that are coupled to the structural design. The fundamental engineering principles were used to derive the structural design catalogue and in the management of surface drainage. Case studies were conducted in the successful application of the design catalogue to demonstrate the approach and design procedures. This approach has made a significant contribution in improving the quality of life of rural communities, particularly in remote and often poor regions of South Africa.
