註釋

This report summarizes small pullout test results conducted as a part of Texas Department of Transportation (TxDOT) Project 5-4829 to assess the performance of a newly developed small pullout box as well as the associated K sub SGI model. The parameter K sub SGI quantifies the stiffness of the soil-reinforcement interface under low displacements, which makes it suitable for evaluating the performance of geosynthetic products in base-reinforced pavements. Seven different types of geosynthetics, including six biaxial geogrids and one geotextile, were tested with three different soil types. Results of each test are summarized in two-page laboratory report format.
