Repurposed materials in construction: A review of low-processed scrap tires in civil engineering applications for disaster risk reduction

摘要

The mechanical properties of waste tires make them an interesting secondary raw material for a wide range of civil engineering applications. Employing whole scrap tires (WSTs) and low-processed scrap tires (LPSTs, i.e. scrap tires that have not been processed by industrial machineries) as a repurposed construction material is a high-value recovery option that requires less resources and energy than recycling. Researchers and practitioners around the world have been able to develop a significant number of innovative and promising WST and LPST applications, particularly for disaster risk reduction (DRR) projects and in vulnerable communities with limited resources. This paper provides a literature review of the current state of the art for the use of WST and LPST in civil engineering applications (CEAs) within the context of DRR. Four main categories of CEAs have been identified according to the primary function of the scrap tire applications presented: earth retaining structures, seismic retrofitting applications, load bearing elements, and drainage systems. The available studies have been organized, classified and discussed in order to take stock of a heterogeneous field of research and highlight areas where further research is needed.
