The objective of this study is to experimentally examine reinforcement methods for the subbase course on which relatively concentrated loads, such as wheel loads act. This study, among many past studies on this subject, is unique in that it mainly deals with vertical reinforcing grid cells by installing reinforcing strips to form grid cells oriented vertically and filling the grid cells with soil.
In this study, triaxial compression tests and CBR penetration tests of specimens having various reinforcing grid shapes were conducted to determine their relationship with grid cells oriented horizontally and their reinforcing efficiencies. Further, to determine the influencing factor on the reinforcement effect of geotextiles oriented vertically in the subbase course, in-situ plate bearing tests were conducted.
The elastic modulus of each layer was then calculated by the finite element method (FEM). Finally, the effect of the geotextiles oriented vertically was evaluated based on the calculated elastic moduli.
