This presented work investigates the valorization of the Municipal Solid Waste Incinerator Bottom Ash in Civil Engineering. The bottom ash from waste incineration consists of, by their origin, a typical granular materials. They are industrial by-products resulting from the incineration of the domestic wastes; and the way of considered valorization is road gravel. In this paper, the geotechnical characteristics of bottom ash taken from a recycling company in the North of France has been presented. The results help to classify our bottom ash according to the technical guide of realization of embankments and subgrades and compare with other bottom ash in the litterature.
