ABSTRACT

Reuse and recycling of waste is no more a challenge, but a demand. Municipal solid waste can be treated through an incineration process that leads to the generation of a residue known as incinerator bottom ash. Previous studies addressed the possibility of using this residue as recycled aggregate in road construction, where it may be in contact with geosynthetics. In the present study, the tensile behaviour of three geotextiles (with different structures and masses per unit area) was assessed after being submitted to mechanical damage under repeated loading tests, in which different aggregates, besides incinerator bottom ash, were used (gravel 4/8, tout-venant and corundum). Results have revealed that incinerator bottom ash did not cause more damage to the geotextiles than most of the studied aggregates. This feature opens good perspectives to consider the possibility of using this residue as recycled aggregate in contact with geosynthetics.
