Rejuvenating old asphalt the bio-way

摘要

In the province of Friesland in northern Netherlands sustainability is a way of life, including when it comes to infrastructure. A flagship project for this region is the widening of the provincial road N381 between Donkerbroek and Oosterwolde. In 2015, the route was expanded from 1×1 lanes to 2×1 by construction company Heijmans. Then in 2018 Heijmans won a contract to widen the road again to 2×2 lanes over a length of 8km. A key reason for the company being chosen for the work was its sustainable approach and circular, high RAP (reclaimed asphalt pavement) ZOAB (porous asphalt) mixtures.
