ConMat’05 Third International Conference on construction materials: performance, innovations and structural implications

[en] Valorisation of Municipal Solid Waste Incineration Residues - excluding ashes - is a positive advance in sustainable development : saving natural resources, decrease of wastes volume stored, reduction of energy consumption. If good conditions of incineration can be ensured and post-combustion treatments are realised, solid residues are in the form of granular materials usable in construction and civil engineering. Application for the fabrication of concrete pavement has been developed. Mechanical and physical performances of municipal solid waste incineration residues let us to replace a part of the granular skeleton and to obtain similar behaviour than for reference granular composition : splitting resistance, water absorption and resistance to abrasion are optimised. Leaching behaviour is also verified in order to avoid detrimental effect on the environment. Example of application is presented in “sleeping policeman” technique and durability of the structure is explained.
