Recycling low-noise SDA asphalt

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.

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.

«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.»
