Rail and Roadway Abutment Reinforcement

The client was considering an alternate system to the traditional reinforced concrete for quicker/easier construction while being environmentally friendly, and cost-saving. The traditional reinforced concrete wall would take much longer to complete and would be quite expensive to construct in this topography.

Titan Solution

Titan provided the design using Pyramid Grid™ for reinforcement behind the East and West abutments of the underpass to increase the factor of safety against global failure. Pyramid Grid™ was the superior solution as it provided significant savings in material cost, construction time, it's easier to install, aesthetically pleasing, and also provided more than 60% Embodied Carbon (EC) reduction.

Titan specifically designed the most optimal configuration for laying the geogrids near the MTS ducts.

Pyramid Grid™ is a high-strength uniaxial polyester geogrid engineered for soil reinforcement, offering exceptional tensile capacity, durability, and stability in demanding construction environments.

Achievement

The use of Pyramid Grid™ in this project delivered a range of significant achievements, including up to 60% savings in both material and construction time compared to conventional reinforced concrete methods. The system enabled fast, easy, and economical installation while allowing the use of on-site fill, reducing the need for imported materials. Its high resistance to dynamic shock loading and seismic activity ensured long-term structural integrity, even in challenging environments. Additionally, the solution minimized traffic disruption and lane closures during construction, provided an aesthetically appealing finish, and demonstrated exceptional durability against harsh soil conditions and environmental factors.
