Abstract(s)With the need to preserve natural resources, waste recovery and recycling are fundamental. However, it is essential to evaluate and characterize the wastes for a correct management namely by incorporation in industrial processes in order to avoid negative impacts. Foundry sand is a waste that can be reused as an aggregate and incorporated in asphalt mixtures. In this work, a mix design study of one asphalt mixture was carried out to assess the maximum amount of material that could be used (5%), together with an evaluation of its water sensitivity.  Additionally the leaching behavior was evaluated. Due to the fluoride concentration, it was concluded that this waste should be sent to a non-hazardous waste landfill, however it does not constitute a limitation on its incorporation in asphalt mixtures which could be an effective process for foundry sand management from both the environmental and economic points of view.
