Abstract
The use of recycled polyester (rPET) in construction materials offers significant benefits, including energy conservation, cost reduction, and decreased solid waste. This study compares the performance of rPET with that of virgin polyester (vPET) products. Therefore, two main testing programs including pull-out tests and creep performance tests were carried out in order to determine the interfacial properties of the geogrid-reinforced soil and time-dependent manner of the geogrids, respectively. Broadly speaking, this study showed that the performance of “rPET” geogrid is comparable with “vPET” geogrids. Pull-out tests revealed that pull-out resistance of both “vPET” and “rPET” geogrids were roughly the same and the “vPET” geogrid mostly had lower dilation angles in comparison with “rPET”. Moreover, based on the performance creep tests, it was understood that the long-term mechanical behaviour of “rPET” does not differ from the long-term behaviour of “vPET” products.
期刊介绍：
An online only, rapid publication journal, Geosynthetics International – an official journal of the International Geosynthetics Society (IGS) – publishes the best information on current geosynthetics technology in research, design innovation, new materials and construction practice.
Topics covered
The whole of geosynthetic materials (including natural fibre products) such as research, behaviour, performance analysis, testing, design, construction methods, case histories and field experience. Geosynthetics International is received by all members of the IGS as part of their membership, and is published in e-only format six times a year.
