Traffic noise is a growing problem, especially for urban areas. The common noise mitigation measures include noise barriers or earthberms that obstruct sound propagation from the roadway to the neighbouring community. Such costly measures are infeasible or ineffective in many urban areas because no actual noise reduction at the source is achieved. Construction of quieter pavements is therefore considered to be a promising technique for economical/sustainable and environmentally friendly highways. This paper is intended to provide an overview of what transportation/pavement engineers or highway agencies/ municipalities need to know about the noise for planning, design and construction of quieter roads. The ranges of sound level for typical highway pavement surface courses/textures including some results of quiet pavement research at the University of Waterloo are also presented to aid the practitioners in selecting surface courses or textures of the pavement.
