The type and condition of a road surface can have a noticeable effect on the noise levels experienced by residents adjacent to state highways.

Guide

We have prepared a Guide to state highway road surface noise to aid our staff and contractors with the design, construction and maintenance of road surfaces. This guide has been produced to inform roading practitioners, contractors and the public about how road surfaces affect noise levels and what low-noise road surfaces are available in different situations. Information is also provided on maintenance issues and basic engineering considerations.

Additional information on low-noise road surfaces is available in:

Case studies

Case studies on projects involving road surfaces are available to supplement those discussed in the guide. The case studies report on key lessons learnt from Transport Agency projects for the benefit of future projects.

Specification

Our requirements for low-noise road surfaces are included in the P40 specification.
