Geogrid in Flexible Pavements

Transportation Research Record: Journal of the Transportation Research Board, 2008
Full-scale accelerated testing was used to provide new insight into quantifying the effectiveness of geogrids on low-volume flexible pavement performance. Although several previous studies report that geogrids improve pavement performance by enhancing structural capacity and reducing distress potential, the new study addresses how to maximize the ...

Soil–Geogrid Interaction at Various Influencing Factors by Pullout Tests with Applications of FBG Sensors

Journal of Materials in Civil Engineering, 2019
The behavior of soil–geogrid interaction is a dominant factor in the long-term performance of geogrid-reinforced earth structures. This study investigates the interaction of sandy soil and the embedded geogrid by pullout tests with the application of a ...

Finite-element modelling of soil-geogrid interaction dealing with the pullout behaviour of geogrids

Acta Mechanica Sinica, 1998
A two dimensional plane-stress finite-element type of analysis is presented to predict the behaviour of geogrids embedded in sand under pullout loading conditions. In the analysis the interactions between soil and geogrid are simulated by non-linear springs.

Connections for geogrid systems

Geotextiles and Geomembranes, 1990
Abstract A general discussion on connection types for geogrid reinforcement systems is presented. The various mechanical and frictional methods for connecting geogrid to geogrid, and geogrid to a structural element are defined in general terms. Basic design guidelines are recommended to assure connection integrity for geogrid reinforcement systems.

Clay bricks with shred geogrids

2010 2nd International Conference on Chemical, Biological and Environmental Engineering, 2010
This session presents a survey and the performance of the role of shred geogrids in mud brick's compressive strength and a comparison of it with the normal mud bricks. Mud brick consists of clay, water and different materials. Its massive use may become an important evaluation due to its low cost and higher compressive strength compared to the concrete

Model geogrids and 3D printing

Geotextiles and Geomembranes, 2017
Abstract This paper summarizes the technical aspects of using 3D printing to fabricate small model geogrids for geotechnical experiments, with the aim of scaling their geometry and tensile behavior under operational conditions, say up to 5% strain. Specifically, we successfully fabricated model geogrids with one-hundredth of the tensile strength of ...

Tensile strength freeze-thaw durability of a biaxial geogrid and wicking geogrid composite

Geosynthetics International
A relatively new geosynthetic material, known as a wicking geogrid composite, consists of a biaxial geogrid bonded to a nonwoven wicking geotextile. This system offers dual functionality by providing structural reinforcement while simultaneously managing moisture in both saturated and unsaturated conditions.

Base Reinforcement with Biaxial Geogrid

Transportation Research Record: Journal of the Transportation Research Board, 2006
In 1986 and 1990, the Georgia Department of Transportation constructed two pavement test sites to evaluate the performance of pavements with base reinforced with biaxial geogrid. The evaluations were conducted by a comparison of results from two control sections with no base reinforcement with the results of three test sections with base reinforced by ...
