- Local construction of the proposed technology adopted for "technology for lightweight embankment"
Regarding "technology related to lightweight embankment," we have used "recycled lightweight aggregate using waste glass" that was proposed by Yazaki Corporation after confirming its performance through test construction.
Overview
Proposed company name
Yazaki Corporation
Proposal content
Recycled lightweight aggregate using waste glass
Proposal Date to TI Network
May 2009
Local trial location
Nihonkai-Tohoku Expressway
Since embankment has been constructed on the soft ground at this location and the embankment has continued to settle for a long period of time, subsidence measures are being implemented. As a countermeasure against subsidence, in the repair work of the step between the bridge and the embankment, we confirmed the effect of suppressing the subsidence speed by using the proposed lightweight aggregate as the embankment material.
Construction status
Since we have confirmed the performance of a lightweight embankment material as an embankment material, we are using it as a measure to control the level difference between the bridge and embankment on soft ground.
Local adoption status
2,900m to Tohoku-Chuo Expressway 3 Was constructed.
In the future, we plan to construct about 18,400 m³ on the Tohoku-Chuo Expressway.
