Modelo de Priorización de Obras Geotécnicas para la Intervención y Mantenimiento de Obras de Infraestructura Vial del CONAVI

Abstract

The national road-network covers approximately 7429 kilometers of which are administered by Consejo Nacional de Vialidad (CONAVI). According to LANAMME studies approximately 58% of the national roads are in areas with geotechnical issues that could affect the state of them. Therefore CONAVI needs tools to help in planning tasks and maintenance of the road-network, so that, to ensure levels of safety, comfort and serviceability appropriate. The proposed model has its focus of study geotechnical infrastructures of the road-network without regarding other infrastructure components. This model aims to help in managing the priorities of the national road-network for optimizing the operation and maintenance of geotechnical issues. This model gathers nine criteria factors taking into account socio-economic, environmental and technical aspects. Through expert consultation, multi-criteria evaluation methods, databases from different sources and geographic information systems determines the proper order of priority As a case of study the model was applied to Oreamuno, Cartago zone. The outcome of the study was that, in general, the area has a medium susceptibility to geotechnical problems and the prioritization level of geotechnical aspects is moderate with some damages that need to be treated.
