Reduction in thickness of Blanket Layer in Railways
Geogrid can be used for reinforcement at the bottom of ballast or at the bottom of blanket or within the blanket, which by its reinforcing/interlocking mechanism forms a semi rigid mat that helps in reducing the stresses on the layer below. This can be used to reduce the required blanket thickness.
To reduce especially the thickness of the Blanket Layer (which is costly granular material obtained by quarrying or mining) in case of new constructions or for formation rehabilitation, on techno-economic considerations and/or to reduce the adverse impact on environment due to quarrying/mining, Geogrid can be used.
