Abstract

Triaxial Geo Grids were first founded in the year of 2007 so as to enable civil engineers to stabilize granular layers subjected to dynamic and static loads. Triaxial geogrid is having a 360° isotropic tensile properties, wherein on laying off the geogrid the aggregates interlock within a triangular slot, for which the efficient deep fibers of the triaxial geogrids assists in confining the aggregate particles. This, in turn, stabilizes the layer and enhances the performance of the subgrade resulting in pavement optimization. Prior to surfacing in the global market triaxial geogrids were under six years of development with a focus on improving the performance under trafficking of the granular layers in which they were included. This involved the use of full-scale testing facilities such as the Transport Research Laboratory (TRL) in the UK. This paper provides a general idea on the possibility to implement Triaxial Geogrids to form a mechanically stabilized layer (MSL) so as to save cost in term of material and construction effort especially in areas where the effective CBR of soil is found to be much below the permissible limit as per IRC specifications thereby extending the design life of the pavement structure. In addition, the proposed MSL would create a flexural stiff platform where the effects of the variable quality of support from the foundation soil can be smoothed out.
