The numerous criteria for technology evaluation in developing countries are discussed with emphasis on labor-intensive appropriate technologies. Historical technologies, current technologies of reduced scale, the adaptation and improvement of indigenous technologies, and the need for research and development in labor-intensive techniaues are presented. The technical factors in road construction are investigated as they relate to labor intensity. Special emphasis is given to evaluation of design standards, location criteria, and scheduling. It is possible to combine labor-intensive techniques where appropriate with more-conventional capital-intensive methods. The susceptibility of the various construction components to labor-intensive application is briefly reviewed. Finally, the barriers to the adoption of labor-intensive techniques in road construction are presented. These include technical barriers; psychological barriers; bureaucratic barriers; educational barriers; managerial barriers; and the general lack of research, development, financing, marketing, and distribution systems to support labor-intensive alternatives. Labor-intensive alternatives are but one in a continuum of technologies. Developing countries will probably retain capital-intensive techniques for primary road projects. Labor-intensive techniques are probably best suited to the construction of feeder and rural-development roads. (Author)
