📋 Tender Overview
A sustainable bicycle bridge made of prestressed geopolymer concrete has been installed for the first time in the route of the Nieuwe N69. The concrete consists of recycled raw materials and no cement is used.This scoop is a good example of the ambition of the province of Noord-Brabant and contractor Boskalis to construct the Nieuwe N69 as the greenest and most sustainable road in Brabant.Never before has a constructive bridge with prestressed geopolymer concrete been performed. Geopolymer concrete has a significantly lower CO2 footprint and is 75 cleaner than traditional concrete. This is because no cement is used and only recycled raw materials are used. No new material is involved. This bicycle bridge is therefore an important breakthrough in innovative power to make more sustainable concrete structures. Boskalis director David Vermeire The core values of Boskalis come together in this innovation. For the first time the entire cycle of development testing production and application has been completed in a real construction with free span. This is the prelude to a new standard for the application of new mixtures with a more sustainable composition.Sustainable PearlThe Nieuwe N69 which is completely energy neutral in its use phase recently received the Sustainable Pearl award from Green Deal Duurzaam GWW. Ineke Bol program manager at the province The New N69 project is characterized by its innovative strength intensive chain collaboration and the courage to go off the beaten track. That was also nicely reflected in this bicycle bridge. Boskalis A. Jansen bv Sqape and the Province of Noord-Brabant together created the optimal conditions to take this major step forward. We went from an innovative idea to realization in record time of three quarters of a year. As a province we think it is important to provide the space for this.Other examples of sustainable developments on the N69 are the innovative noise-reducing asphalt surface. It is made with 70 recycled materials making it 45 more sustainable than the standard asphalt surfacing. In addition solar panels are installed in sound barriers of stream valley bridges biodiesel is used and sustainability is also taken into account in the designs of bridges. The bridges are slender and slim so that less concrete is needed.
