Abstract

Resumen: En Colombia, los bajos niveles de servicio de las vías terciarias afectan el desarrollo económico y, especialmente, el desarrollo rural. Ante las limitaciones presupuestales de los municipios, es importante contar con métodos de mantenimiento preventivo y correctivo de bajo costo frente a las alternativas existentes. La estabilización de suelos con subproductos industriales procesados es una alternativa para mejorar los niveles de servicio de las vías y para reducir la producción de sedimentos. En este artículo se presenta un caso de estudio en el que se usan tres subproductos industriales procesados para la estabilización de un tramo de vía en Urrao, Antioquia. Para estimar los costos de la estabilización usando dichos subproductos, se adaptó el análisis de costos del ciclo de vida, en el que, además, se consideraron factores técnicos, geográficos y de disponibilidad de materiales. Se encontró que el costo de estabilización es muy sensible a la disponibilidad y ubicación de materiales, al volumen procesado y al costo de transporte. Abstract: Low serviceability of rural road networks in Colombia hinders economic development, and especially rural development. Municipalities have budget constraints, so it is important to develop low cost techniques for preventive and corrective maintenance of rural roads. Stabilization of rural roads using industrial by-products is an alternative to improve road conditions and to prevent negative impacts from sediment production. This paper presents a case study in which three non-commercial materials produced from industrial waste are used for stabilizing a road section in Urrao, Antioquia. Stabilization costs are compared for the three alternatives by adapting the life cycle cost analysis to the information available. In addition, assessed costs consider geographic and technical factors, as well as availability of residues. It is found that stabilization costs are highly sensitive to waste availability and location, to processed volumes and to transportation costs.
