REPORT: Evaluation of Anchor Systems Through Full Scale Pullout Testing


This paper discusses the testing methodology and results of a research program that evaluated the pullout resistance of several commonly used turf reinforcement mat (TRM) anchoring systems. The testing was full-scale and used soils with known mechanical properties. The results provide quantitative performance differences based on the design, size, and embedment depth of the chosen anchor(s). The paper describes the design, construction, and use of the test apparatus; details the performance characteristics of the anchor systems evaluated; recommends further research; and encourages the adoption of a standardized full scale anchor system pull out test for the evaluation of anchor systems designed to be used in turf reinforcement matting installations.

Keywords: erosion control, performance testing, High Performance Turf Reinforcement Matting, HPTRM, anchor system, full-scale testing
