Road surface acoustics – we are the leader.
Determining the acoustic quality of road surfaces.
Our services include measurements to determine the acoustic quality of road surfaces, e.g. with the CPX trailer measurement method, as well as specific measurement procedures and analyses for the acoustic optimisation of road surfaces. Our customers benefit from comprehensive strategic and technical advice on the planning, installation and maintenance of quiet road surfaces.
Supposedly identical road surfaces can sometimes have very different noise effects, or the acoustic effect can change over time. With our pavement acoustic impact analyses, we get to the bottom of the causes. To maintain the long-term acoustic effect of the road surfaces, we develop solution proposals based on pollution degree and surface texture analyses.

Many municipalities lack reliable data on the condition of their road networks. The municipality of Glarus is changing that. Since March 2025, it has been using vialytics – a system that automatically assesses road conditions using a smartphone camera and artificial intelligence.
As the exclusive Swiss partner of vialytics, Grolimund + Partner AG supported the municipality in implementing the technology and laid the foundation for modern, data-driven road management.
CPX Season 2024
The G+P pavement acoustics team has been carrying out close-proximity measurements (CPX) throughout Switzerland since 2008. The eventful 2024 CPX measurement season came to an end with the first snowfall at the end of November. While initial preparations for next year are already being planned and organised, we would like to summarise the 2024 CPX measurement season at the end of the year.
