[WIB Construction Method Case Study] Traffic Vibration Mitigation for New Roads

Confirmed a reduction of more than 10dB, with vibrations reduced to one-third or less! Measures have been implemented directly beneath the road!

In Yamanashi Prefecture, with the establishment of new embankment roads, it became necessary to preserve the environment of residential areas along the route after the road opened. Therefore, the 'WIB method' was implemented directly beneath the road. A running test using a backhoe was conducted before and after the countermeasures (before road construction). As a result, a reduction of more than 10 dB was confirmed in both horizontal and vertical directions near the boundary between public and private land, and vibrations were reduced to less than one-third. [Case Summary] ■ Construction Location: Yamanashi Prefecture ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Several residential buildings along the road ■ Countermeasure Work: Plate-type WIB (honeycomb cell type) ■ Construction Position: Directly beneath the vibration source *For more details, please refer to the PDF document or feel free to contact us.
