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.

«Even after 17 years at G+P, I deal with new issues and challenges almost every day. The solutions are often developed in interdisciplinary and cross-branch teams. This confrontation with exciting technical issues and the exchange with a highly qualified team motivate me again and again.»

Team

«Working with and for different clients allows me to gain insight into a wide variety of fields of activity. At G+P itself, we work in interdisciplinary teams across the various specialist areas to find solutions. The focus is often on the goal of providing more peace and quiet for the population. I also really appreciate the fact that I can work in several branches and at home, and that the PC-heavy work is always broken up by measurement work outside with the CPX drivers, alone and with office colleagues.»

«As an energy and sustainability consultant, I enjoy supporting clients in making their buildings more durable, comfortable, productive and efficient. I am particularly fascinated by the systemic interrelationships and finding holistic solutions in this context.»

«I have been with G+P AG for over 20 years. I appreciate the good cooperation and the lively exchange of information in the team. I can contribute my extensive practical construction knowledge and experience to the team, on the construction sites, when problems arise or in the event of construction damage. The knowledge gained from construction damage is passed on as an ongoing learning process within the team. As of October 2022, I will be partially retired and will continue to work at G+P AG with a workload of 40%. I spend a lot of time in the mountains (climbing, ski touring) as compensation.»

«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

«I have been working for G+P on a part-time basis for more than 20 years, and thanks to G+P's great flexibility I have been able to combine family and career wonderfully. I experience G+P as a dynamic team and a generous employer in all respects, from the coffee and croissants on offer, the great employee events, to the generous BVG insurance benefits. I am proud to work for G+P.»

«Noise pollution reduces the quality of life of those who suffer from it. My goal is to reduce them as much as possible – G+P provides me with the means to do this. Street noise and shooting noise - I have been able to develop in these areas thanks to the skills acquired in a dynamic, friendly and stimulating working environment.»
