TERRAMESH REINFORCED SOIL WALL TO APPROACH A RAILWAY OVER BRIDGE (

Punjab State Roads & Bridges Dept. allotted the project on BOOT basis (Build Own Operate & Transfer). As a part of the Road widening measures and Improvements to the Highway along Ambala – Kalka Road, a Railway Over Bridge was proposed over the Railway crossing along New Delhi – Chandigarh line at Derabassi. It consisted of around 500m of Approach Embankments on either side of the R.O.B. The Height of the Embankment ranges from 1m to 12m near the abutment. Keeping in mind the ease in construction along with its Environment Friendliness, Terramesh System was proposed. The total facia area was around 12,000 Sqm. Another factor favouring the use of the Terramesh System was inherent flexible nature of the System due to the presence of poor foundation soils, comprising of silt with traces of clay. Hence a 0.30m basal mattress was also provided as an apron protection.
