Geogrid mechanical damage caused by recycled construction and demolition waste (RCDW) under in-field cyclic loading

Abstract: Despite the advances observed over the last decade, Brazil still suffers from the scarce use of recycled construction and demolition waste (RCDW). On the other hand, most of the roads in the country are unpaved and present low loading support. In this context, the construction of geosynthetic reinforced unpaved roads with RCDW could stimulate the market of recycled materials and increase the performance of these roads. This study aims to evaluate the mechanical damage of two types of geogrids due to in-field c… Show more

“…The meshes were curled, wrapped in bubble wrap, and transported to the Geosynthetics Laboratory of the São Carlos School of Engineering to perform tensile strength tests. Overall, this process was similar to the ones adopted by Fleury et al [47], Barbosa and Santos [58], and Barbosa et al [68]. Figure 2 illustrates some stages of the damage simulation procedure.…”

“…Moreover, considering dropping particles near the top of the pile inside the dump truck, the impact could be with higher energy. Previous studies by Barbosa and Santos [58] and Fleury et al [47] investigated the damage caused by the backfill drop material. They reported reduction factors lower than 1.12 and highlighted that the damage did not increase with the drop height.…”

“…FIGURA 3: Faixa granulométrica da ARM versus especificações internacionais. A Figura 4 apresenta algumas das curvas granulométricas de areias que foram produzidas na mesma usina de beneficiamento da ARM (Dias, 2014;Britto, 2020;Oliveira, 2020) e outras que foram ensaiadas por outros pesquisadores da Universidade de Pernambuco (UPE) (Couto e Santos, 2016;Silva e Santos, 2016;Rosa e Santos, 2016;Barbosa, Santos e Gusmão, 2021). Observou-se que praticamente todas as areias recicladas analisadas atenderam as faixas inferiores das normativas internacionais.…”

“…Pesquisas desenvolvidas no âmbito da ICC buscam inserir os RCC a partir de práticas, com destaque a reciclagem ou a reutilização em suas distintas atividades como materiais agregados a partir de resíduos classificados como classe "A" [12,13], tais como o uso em argamassas [14][15][16][17], em concretos [18][19][20][21][22][23][24], e até mesmo como material de base para obras de infraestrutura de pavimentação [25]. No ramo da engenharia geotécnica, estudos que abordam a inserção de RCC têm ganhado notoriedade, tais como o emprego como material de aterro em estruturas de contenção [26][27][28][29], camada drenante em aterro de resíduos [30], preenchimento de estruturas de reforço com geossintéticos em rodovias [31,32], dentre outros.…”
