Chacha Chacha, Ximena Valeria Castillo, Tito desperdicios pavimentación Lean Construction is a philosophy than is oriented in the management of construction projects following the principles of continuous improvement, whose main objective is to reduce or eliminate activities that do not add value and optimize the activities that do, showing results in a decrease of the cost, an increase of the quality and a reduction in the term of delivery of the constructions. The tools of this philosophy have been implemented in the construction of buildings, housing and mining. However, in pavement infrastructure projects, little has been investigated. The purpose of the present research work is to identify the wastes in the paving construction processes applying the Lean philosophy.

Las herramientas de esta filosofía han sido implementadas en la construcción de edificios, viviendas y minería. Sin embargo, en proyectos de infraestructura de pavimentos es poco lo que se ha investigado. El propósito de la presente investigación es identificar los desperdicios en los procesos constructivos de pavimentación aplicando la filosofía Lean. Para el efecto se realizó un análisis comparativo entre dos empresas dedicadas a construcciones viales para evaluar los desperdicios generados. Se tomaron datos en campo diariamente mediante la grabación de videos y registros de formularios. Los resultados de este estudio confirman que los procesos son afectados por las mismas causas que en otros tipos de proyectos de construcción, aunque en menor porcentaje, pues las obras viales presentan mayor trabajo productivo debido al efecto del sistema de flujo continuo característico de estas obras. La forma en que el sistema de producción afecta la reducción de pérdidas requiere un estudio más amplio.
