Title:

Engineered Cement-based Composite Systems for Expansion Joint-free Bridges (Jt-Free)

Value Proposition:

Engineered cement-based composite systems for expansion joint-free bridges (Jt-Free) with high tensile performance that can replace conventional expansion joints – leads to joint maintenance-free bridges with long service life.

Summary Application:
  • Engineered cement-based composite systems for expansion joint-free bridges (Jt-Free) can be used as a replacement to conventional expansion joints and aid in development of expansion-joint free bridge deck systems.
  • Applicable to any environmental exposure condition, high temperature variation
  • Effective for easy and fast replacement of the existing metallic or polymeric expansion joint and completely maintenance-free
  • Due to the efficient design, low cost to performance ratio and high durability, this novel Jt-Free will be a game changer in bridge industry with huge socio-economic impact.
Advantages:
  • Technology to overcome the perennial problems of conventional expansion joint-related problems in bridges
  • Developed composite system will
    • Significantly increase the service life of bridges
    • Offer riding comfort as it can make the bridges joint-free
    • Improve the fuel efficiency of vehicles
    • Reduce the maintenance demand for bridges
  • Due to the less reinforcement demand, implementation will be easy
  • Can be implemented in new as well as existing bridges
  • Life-cycle cost of the technology is very low compared to conventional expansion joints
