TRENDS IN THE USE OF CINDERS OBTAINED FROM THE INCINERATION OF HOUSEHOLD REFUSE IN ROAD CONSTRUCTION

PERSPECTIVES D'UTILISATION DES MACHEFERS D'INCINERATION D'ORDURES MENAGERES EN TECHNIQUE ROUTIERE

Details are given of the main geotechnical, physical and chemical characteristics of cinders from the two largest incineration plants in the Paris region. Laboratory studies enabled the very low water intake of the cinders (compressive strength: 8 bars at 360 days and 14 bars at 3 years) to be observed but in-situ investigations have proved that the compressive strength of cinders could exceed 50 bars. These studies also showed that this water intake is often accompanied by swelling phenomena, the extent of which appeared to be related to 80 micron screenings and fire losses at 400 and 1000 deg. It is proposed that, for each different use of cinders in pavement structures, specifications should be drawn up. Emphasis is placed on the fact that the use of cinders in basecourses, with or without stabilization with hydraulic binders, is still at the experimental stage. /TRRL/
