Recycling low-noise SDA asphalt

Over the past years, several hundred kilometres of highly effective low-noise SDA 4 road surfaces have been constructed across Switzerland. Many of these sections are now approaching an age at which replacement will soon be required. One aspect has so far received little attention: these specialised surfaces cannot be recycled as easily as conventional road materials. This issue will become increasingly relevant in the coming years. By 2030, more than 200,000 tonnes of SDA material are expected to arise and will need to be reused in a technically sound manner.

3D City Models as a Tool for Noise Control

How loud are our cities – today and in the future? Using the example of the city of Uster, G+P shows how traffic noise can be made visible in realistic 3D city models. These detailed virtual representations of the real environment provide a solid basis for planning, communication and targeted noise mitigation.

One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

«As part of G+P's external noise team, I particularly appreciate the professional exchange within the core team, as well as the constructive collaboration with other teams. Due to the diversity of projects, both in the public and private sector, new and exciting challenges always open up. Furthermore, it is nice to see that we are able to contribute to a "low-noise and quieter world" with our innovative solutions.»

«The welcome that G+P gave me when I arrived at 2022 was overwhelming. I immediately felt at home in the company. The projects are varied and very interesting and the people at G+P are always willing to collaborate and help, which is the strength of our team.»

«I find it exciting and enriching to exchange ideas across disciplines in the G+P team. Everyone contributes their own experience and expertise, whether it's during a project meeting, a coffee break or an after-work beer. We always come up with creative and goal-oriented solutions for our customers, even for particularly challenging problems.»

Christian Merkli

«I have been at G+P for just over a year as a project leader in research and development. I have learned a lot about road acoustics and their measurement in the past year, as G+P is a pioneer in this field in Switzerland. At the same time, there is always room to bring my skills and experience to the table, while developing new ones.»

Peter Mikhailenko

«What I appreciate about G+P is the extremely broad field of activity, which ranges from normal project work to conference participation and international research collaboration. Likewise, I think it's great that the coffee break can be actively used to compare current conditions in the mountains, which creates a welcome balance between work and free time.»

«At G+P, I particularly appreciate the mutual helpfulness as well as the opportunity to specialize and develop within different subject areas. Due to the diversity of our projects, I am constantly faced with new and interesting challenges in my day-to-day work.»

«Thanks to G+P, I have the opportunity to develop my skills in a dynamic and friendly professional environment. The projects I'm involved in are varied and stimulating, offering the chance to make tangible improvements to the daily lives and quality of life of many people by protecting them from noise pollution.»

Antoine Thévenaz

Team

«There are good reasons why I have been working at G+P since 1996: I have always been able to familiarize myself with new areas, receive further training and help build innovative solutions. During this time, my children were born and grew up – the flexibility of G+P in terms of workload and working hours was and is invaluable. I love the working atmosphere, where you can bring in and implement your own ideas, even for new work processes.»

Nicole Freuler

Team

«I have been with G+P for over ten years and enjoy the diverse projects and interesting technical problems that our work brings. I can say with confidence that the team is going from strength to strength.»

David Murton

«What I appreciate most about G+P is the wide range of building physics topics that we are able to deal with on a daily basis as part of an outstanding team. It is a personal concern of mine to support and accompany our customers every day on their way to greater energy efficiency and sustainability. In this way, I can make a personal contribution to a ‘greener’ world of tomorrow, both for the general public and for my two small children, for whom I have plenty of time thanks to my ‘daddy day’ and 80% workload.»
