An Ecotechnical Alternative: An Embankment of Incinerated Municipal Solid Waste

Incineration seems to be one of the best solutions to solve the problem of household refuse disposal. In compliance with European legislation, part of this incinerated refuse, could be used in public works. The authorities are fully aware of the high economic stakes involved, and this is the reason why they would like to control and define the conditions of use of such incinerated refuse. An innovative alternative is presented in this paper, involving the use of slag from Municipal Solid Waste Incineration (I.M.S.W.R.), lightened by the inclusion of old tyres, and strengthened with a layer of geosynthetics, in order to build a retaining wall for a road embankment. With the possibility of seeding the wall facing, the structure can be blended harmoniously into the site. This reinforced structure was monitored in order to check its behavior, especially its thermal behavior
