Road Traffic Noise of Expansion Joints - Get a Grip on it

摘要

Expansion joints used in road traffic bridges can be a serious source of noise nuisance. This is caused by the impulsiveness of the sound of vehicles passing over the joints and sometimes the presence of low frequencies in the sound. In the Netherlands large-scale application of low noise road surfaces creates a need for low noise expansion joints. Therefore Rijkswaterstaat has created a guideline to deal with noise of expansion joints. The goal is to avoid excessive noise problems by setting noise limits in contracts. The approach in the guideline is based on existing calculation and measurement methods with which there is already considerable experience in the field of low-noise road surfaces. The application of these methods to the noise caused by expansion joints is new.
