Short-term tensile behaviour of three geosynthetics after exposure to Recycled Construction and Demolition materials

Designing and building structures infrastructures with alternative environmentally friendly materials is, nowadays, an important step towards a more sustainable society. Recycled Construction Demolition (C&D) have been considered as in different civil engineering applications, such unbound pavement layers structural embankments, which geosynthetics are also frequently applied. If the durability of is issue when conventional used, it becomes relevant utilising materials. This paper presents discusses chemical environmental degradation induced by recycled C&D material on short-term tensile behaviour three used typically reinforcement (two geogrids high-strength geotextile), after 24 months exposure. For comparison purposes, samples were exposed to natural soil. The physical characterization presented intact (as-received) samples, immediately exhumed exposure characterized discussed. To evaluate potential damage detail, Scanning Electron Microscope (SEM) analyses carried out. Regardless geosynthetic type condition, geosynthetic’s strength decreased 24-month loss was insignificant for high density polyethylene geogrid higher geotextile. effect exposing had some relevance only both geogrids, specimens through comparable. In general, or soil similar effects.
