This project site is located at Patli, approximately 35 km away from Gurgaon, Haryana. It is Railway siding project of Adani Logistics which comes under the Northern Railway zone. Since mining is restricted in India due to environmental concerns, the blanket material for railway formation was not available in nearby area of project site and had to be procured from far places which would in turn increase the project cost. With this constraint in view, the engineers were looking for a solution minimizing blanket (subballast) material with same performance and economical. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Geosynthetic solutions play a vital role as alternative to conventional approach in track bed stabilization projects. The design was based on modified method authored by P. Rimoldi which is extension of Leng and Gabr method. As per RDSO guideline, Extruded Polypropylene Bi-axial MacGrid EG geogrid with 30 kN\/m tensile strength and 38mm X 38mm aperture size was adopted. Non woven (MacTex N 60.1) needle punched geotextile was used as separator & filter layer. Geotextile is placed at interface of blanket & subgrade layer. MacGrid EG was used for reducing the blanket layer thickness from 0.6m to 0.3m for heavy axle load railway line (i.e. 32.5 ton). MacGrid EG was placed at middle of blanket layer. MacGrid EG stabilizes the blanket layer by ensuring lateral confinement of granular material, tension membrane effect and improved bearing capacity. MacTex N is permeable layer which allows water to pass through it and it avoids the intermixing of blanket layer & prepared subgrade. Thesolution turned out to be the viable option in saving material, labor and time along with reduction in carbon footprint. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
