Abstract
Waste foundry sand (WFS) originating in the automotive industry landed more than thirty years ago was collected in an industrial waste sanitary landfill. With this WFS, hot mix asphalt mixtures (HMA) containing this WFS were produced by replacing the fine aggregate (in this case manufactured sand) and cylindrical asphalt concrete specimens (CAC) by the Marshall method was produced. In the environmental characterization of leaching and solubilization of these HMA analysed by scanning electron microscope by dispersive X-ray spectroscopy (SEM/XSE), it was concluded that substances present in the WFS were encapsulated definitively by the HMA asphalt matrix.
