Minimising noise from expansion joints

14:25 - 14:50

Noise generated by traffic crossing road bridges can be a major source of disturbance for local communities and must be carefully considered in planning bridge construction and maintenance projects – especially when specifying expansion joint solutions, since expansion joints are typically mechanical components that introduce discontinuities or unevenness into an otherwise smooth driving surface. The consequences of not adequately considering the potential impact of noise on a community can be substantial, with public relations difficulties and high adaptation or replacement costs.

This presentation explores the subject of noise associated with bridge expansion joints, including an assessment of what types of joint may be considered quiet such as modern flexible plug expansion joint made of special polyurethane material, and how noisier types – such as modular or single-gap joints – may be made quieter, illustrated with case studies including the Queensferry Crossing.
