Research and development (Repair Engineering Institute)

Main Building Our technologies are useful in maintaining roads, bridges, ports, buildings, and other structures.
We will continue conducting research on materials and enhancing the methods and installation technologies that form the basis for all that.

Mobile Loading Test Laboratory 1.
Large scale Experiment Laboratory
2.
Research Laboratory
3.
  1. This mobile load tester facilitates experiments under wheel loads approximating real ones.
  2. Fatigue and load tests are conducted on life-size samples.
  3. An Electron Probe Micro Analyzer (EPMA) is used to analyze and evaluate high polymers and other materials in terms of both chemistry and physics.
