Geosynthetics are widely used in landfill cover systems for various purposes. The stability of these geosynthetics on slopes of landfill covers depends on the effectiveness of the anchors in which these are embedded at the top of the slope. These geosynthetics are subjected to pullout forces that are in an inclined direction. However, only two studies have been reported so far on the inclined pullout behavior of geosynthetics embedded in various types of anchors. In this study, a new inclined pullout device is developed to conduct pullout tests under different angles of inclinations. The salient features and details of various components of this device are presented in this article. Because geogrids are the preferred choice for veneer reinforcement, inclined pullout tests are conducted on geogrids embedded in three different types of anchor, namely, run-out, I-type, and L-type anchors. The tests are conducted on two different types of sands, i.e., quarry sand and river sand. The results show that the peak pullout force increases significantly as the inclination of the pullout force increases for all three types of anchor and for both the sands. Moreover, the complete pullout force-displacement response is found to be different for the three anchors. Practical implications of the outcome of the study are given.
