To improve a structure’s mechanical properties or performance, mechanically stabilized embankments and geosynthetic-reinforced structures are used due to their affordability and efficiency. Civil engineering structures that incorporate geosynthetic materials are referred to as geosynthetic-reinforced structures. Nevertheless, there are some scenarios in which they can fail, such as withdrawal of the geosynthetics. The pullout test is a typical procedure used to assess the strength of the interface between a geosynthetic material (such as polymeric strips, geotextiles, geogrids, or geomembranes) and the surrounding soil or other materials with which it comes into contact. Many researchers have carried out studies that concentrate on the variety of parameters, including variations in the reinforcement geometry, fill material, and its moisture content, compaction, and loading conditions, as well as variations in the pullout material and pullout process. Useful from the point of view of sustainability studies on construction and demolition waste material as fill material is also conducted. This document provides a thorough summary of important research findings from several studies investigating the effects of changing different factors on pullout test results. The thorough investigation leads to the conclusion that, with the assistance of existing research, an appropriate pullout technique and test conditions must be developed.
