[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 made of high-damping material was filled within a grid. Renovation work was carried out on the side road that runs between the national highway and the residential area, and the 'WIB method' was implemented directly beneath the road. After conducting vibration measurements before and after the countermeasures, a reduction of 4 to 5 dB in vertical direction was confirmed near the boundary between public and private land. 【Case Summary】 ■ 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.
