However, it is responsible for more than 50% of the depletion of natural resources, for 40% of the energy consumption and construction and demolition waste (CDW) accounting for 30\u201360% of the total municipal solid waste generated worldwide. In this sense, the recycling of CDW is considered a safe alternative to the current trend, which can produce environmental and economic benefits, namely the reduction of the depletion of natural resources and the volume of waste sent to landfills. Some studies have shown promising results in the use of recycled CDW as geotechnical materials. However, the degradation performance induced by the construction procedures and weather conditions on the geotechnical behaviour of recycled CDW is still a research gap, creating an obstacle for its regular use in general engineering practice. This work evaluated the mechanical performance of recycled CDW over time when subjected to wetting\u2013drying degradation cycles under different temperature and pH conditions. The effects of such degradation were then evaluated qualitatively (changes in particle size distribution and Proctor parameters) and quantitatively (stress\u2013strain response and permeability). The results showed that 10 wetting\u2013drying cycles and different compaction energies have no change in the particle size distribution of CDW compared to the original CDW. The shear strength parameters were very similar for the different degradation conditions except when different pH values were used, which may have weakened the grains and decrease the friction angle of the material. Regarding the permeability, all tested samples were classified in the same hydraulic conductivity range (very low) without significant changes induced by the degradation mechanisms.<\/jats:p>","DOI":"10.3390\/su14116719","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T05:25:42Z","timestamp":1653974742000},"page":"6719","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Geomechanical Behaviour of Recycled Construction and Demolition Waste Submitted to Accelerated Wear"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8938-1003","authenticated-orcid":false,"given":"Marina Paula","family":"Secco","sequence":"first","affiliation":[{"name":"Centro de Qu\u00edmica\u2013Vila Real (CQ-VR), University of Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0133-8308","authenticated-orcid":false,"given":"Giovani Jordi","family":"Bruschi","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica\u2013Vila Real (CQ-VR), University of Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6328-4504","authenticated-orcid":false,"given":"Castorina S.","family":"Vieira","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3600-1094","authenticated-orcid":false,"given":"Nuno","family":"Cristelo","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica\u2013Vila Real (CQ-VR), University of Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105805","DOI":"10.1016\/j.resconrec.2021.105805","article-title":"Environmental impacts of cross-regional mobility of construction and demolition waste: An Australia Study","volume":"174","author":"Wu","year":"2021","journal-title":"Resour.
