Abstract
El presente trabajo de investigación se realizó en el distrito de Simbal, provincia de
Trujillo, departamento de La Libertad, donde se realizó el análisis comparativo de
costo y tiempo con los diseños de pavimento de losas optimizadas, tradicionales y
flexible, para lo cual se empleó un diseño no experimental, transversal y descriptivo;
donde se evaluó tres poblaciones representados por los tipos de diseño mencionados
asimismo se realizaron los estudios de tránsito, mecánica de suelos y topografía para
la obtención de datos, para el análisis de datos se usó la técnica estadística
descriptiva, el problema radica en que a lo largo de los años se ha venido
pavimentando tradicionalmente con un pavimento flexible; que frente al pasar de los
años así como al tráfico de vehículos circulantes la vida útil de los mismos ha bajado,
representándose en fallas de la carpeta de rodadura, ocasionando que se eleve el costo
de la vida útil del pavimento, por otra parte en Trujillo y en el Perú no es muy usado
la pavimentación con concreto y mucho menos las nuevas metodologías que se
desarrollan en base a esto como es la técnica de lozas optimizadas en las que se tiene
pocos profesionales especializados en este campo, se obtuvo que para un periodo de
diseño de 20 años la estructura diseñada con losas optimizadas de concreto presenta
ventajas significativas de costos frente a los pavimentos de concreto rígido y asfalto
tradicional llegando a un valor estimado mediante un análisis de costo de ciclo de
vida de S/ 1,937,892.54, S/ 2,038,850.15 y S/ 2,404,112.99; en relación al tiempo
esperado mediante el método de la ruta crítica la relación está entre 90, 80 y 49 días
calendarios y empleando la técnica de evaluación y revisión de programas se estimó
un tiempo de 102, 95 y 51 días calendarios respectivamente. Del análisis comparativo
se concluyó que el diseño con losas optimizadas presenta menores costos para un
periodo de análisis de 20 años y un tiempo de construcción no significativo en
comparación con las otras metodologías.
The present research work was carried out in the district of Simbal, province of Trujillo, department of La Libertad, where the comparative analysis of cost and time was carried out with the optimized, traditional and flexible slab pavement designs, for which a non-experimental study, cross-sectional and descriptive design; where three populations represented by the types of design mentioned were evaluated, traffic studies, soil mechanics and topography were also carried out to obtain data, for the analysis of the data the descriptive statistical technique was used, the problem is that throughout Over the years it has traditionally been used paved with flexible pavement; that over the years, as well as the traffic of circulating vehicles, its useful life has decreased, generating failures in the rolling surface, causing the cost of the useful life of the pavement to increase, on the other hand in Trujillo and Peru concrete pavement is not widely used, much less the new methodologies that are developed based on it, such as the optimized tile technique in which there are few professionals specialized in this field, it was obtained that for a design period of 20 years . , the structure designed with optimized concrete slabs presents important cost advantages over traditional rigid concrete and asphalt pavements, reaching an estimated value through a life cycle cost analysis of S/ 1,937,892.54, S/ 2,038,850.15 and S/ 2,404,112.99 ; In relation to the expected time using the critical path method, the relationship is between 90, 80 and 49 calendar days and using the program evaluation and review technique, a time of 102, 95 and 51 calendar days was estimated respectively. From the comparative analysis, it was concluded that the design with optimized slabs presents lower costs for an analysis period of 20 years and a non-significant construction time compared to the other methodologies.
