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.

Low-noise road surfaces – Complete advice from a single source
Nowadays, a road surface must not only fulfil safety aspects. It should also be as cheap and durable as possible, be able to withstand the emerging traffic load and cause as little noise as possible in densely built-up Switzerland. Low-noise road surfaces are often a good choice here. However, the enforcement authorities responsible for the roads are repeatedly confronted with the following questions: How noisy is the existing pavement? Which low-noise pavement is optimal on which road section? How effective is the newly installed low-noise pavement? Is there potential for optimisation? Grolimund und Partner provides answers to these questions.
