Abstract
En la ejecución del proyecto: Mejoramiento de la Ruta Nacional No. 622 Sección: Esparza – Juanilama - Salinas, se obtuvieron los siguientes resultados:
La ausencia de datos sobre el diseño del pavimento (vida útil, tránsito) y la falta de una evaluación previa de la condición de la Subbase existente, son prueba de que el estudio básico del proyecto estuvo incompleto antes de publicar la licitación para construir esta obra.
No se encontraron evidencias de la aplicación del sistema de medición y pago de estimaciones que se estipula en el Manual de Construcción MC-83, en el código CR-77.
La labor de bacheo con mezcla asfáltica no fue registrada adecuadamente y no tiene soporte preciso de las cantidades y sitios de colocación de esta mezcla.

No evidence was found of the application of the measurement and payment of estimates system stipulated in the MC-83 Construction Manual, in the code CR-77. The work of patching with asphalt mixture was not recorded properly and does not have precise support of the quantities and placement sites of this mixture.
