After understanding the needs of the client and the project, Terre Armée India proposed a unique solution of TechAbutment® system along with Reinforced Earth® Wall solution to create an integrated innovative engineering solution to help client realise their project without any technical compromises, with economic gain and time advantage.
Since, the geotechnical property of the foundation soil was not good, Terre Armée India proposed ground improvement and it was accepted by the client and the contractor.
TechAbutment® system is a true abutment where RCC Griders or Deck slabs are directly rested on Reinforced Earth® Walls. The uniqueness of this solution is that the conventional RCC abutments can be completely replaced with discrete panels, which provides better aesthetics also. TechAbutment® system was proposed at closing wall and return wall up to the length where the wall is subject to the bridge load. Considering the high loads, inextensible soil reinforcements were adopted. Terre Armée India adopted High Adherence Galvanized Steel Strips® to construct safe and sustainable true abutment solution.
For the approach ramp, Terre Armée India proposed to adopt GeoMega® system where GeoStrap5 soil reinforcing strips were used. Terre Armée India was responsible for design, sourcing of specialized materials and technical assistance at site for pre-casting and installation activities. The project was completed successfully within a span of 13 months.
