[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Residential Areas Along National Highways

Vibration measurements were conducted before and after the measures were implemented! A reduction of 4 to 5 dB in the vertical direction was confirmed!

In Saitama City, Saitama Prefecture, traffic vibrations from the national highway were affecting the living environment along the route, leading to complaints from residents. As a countermeasure, tire shred with high damping material was filled in the grid. Renovation work was carried out on the side road that runs between the national highway and residential areas, and the 'WIB method' was implemented directly beneath the road. Vibration measurements were conducted before and after the countermeasures, confirming a reduction of 4-5 dB in the vertical direction near the boundary between public and private properties. 【Case Overview】 ■ Construction Location: Saitama Prefecture ■ Client: Saitama City ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Several residential buildings along the national highway ■ Countermeasure Work: Wall-type WIB method (grid type) ■ Construction Position: Vibration propagation path *For more details, please refer to the PDF document or feel free to contact us.
