[WIB Construction Method Case Study] Traffic Vibration Mitigation for Existing Roads
Conducted driving tests with a 10-ton truck before and after the measures! We were able to achieve vibration reduction effects!
In Shizuoka Prefecture, vibration countermeasures were required in areas where complaints about vibrations had been occurring during road renovation work. As a result, the 'WIB method' was implemented directly beneath the road. Before and after the countermeasures, driving tests were conducted using a 10-ton truck. Vibration responses were measured and compared at the boundary between public and private properties along the road, on the ground within the site, and on the second floor of buildings. It was found that vibrations around the dominant frequency of 6Hz were reduced, achieving an average reduction of 10dB in the horizontal direction and 20dB in the vertical direction.
