Road maintenance and repairing works are usually required to be carried out at the less busy night hours to avoid causing serious interruption to heavily trafficked roads during daytime. Quieter equipment or methods for night-time works are needed to minimise the construction noise impact.
Noise reduction for some mitigation measures for reference.
Quieter Construction Methods
The Quieter Type Blade saw with higher speed and smoother balde reduces the excitation of vibration and hence the propagation of sound.
