THE OPTIMUM USE OF NATURAL MATERIALS FOR LIGHTLY TRAFFICKED ROADS IN DEVELOPING COUNTRIES

The planning, construction and maintenance of lightly trafficked roads are discussed, with particular reference to the optimal use of local materials and resources. Attention is drawn to the importance of terrain evaluation techniques for improved road location and construction material surveys. The importance of an intimate knowledge and appreciation of local conditions and terrain for optimum serviceability is stressed. Foreign aid often covers only the planning and construction phases of development and loses interest during the maintenance after completion. This aspect is of particular importance to the financing institutions to expand the export of expertise and equipment for maintenance. The importance of, and examples illustrating procedures to promote labour intensiveness in highway construction in developing countries is mentioned. Examples of materials standards for gravel surfaced lightly trafficked roads, and the experience on which they are based, as well as the novel applications of certain natural resources are discussed. Geometric standards and drainage applications that have been found to be particularly practical are highlighted. Approximate cost estimates are included for the various grades of roads discussed. /Authors/
