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.
Road Works
Noise enclosure Installation grind wheel covered by the noise enclosure.
Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.
An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.
The Quieter Type Blade saw with higher speed and smoother balde reduces the excitation of vibration and hence the propagation of sound.
QPME or Quality Powered Mechanical Equipment items, are construction equipment items that are new, notably quieter, more environmentally friendly and efficient.
