In 1990, Switzerland crushed an old A13 road and reused 66% to 100% of it in new concrete; 20 years later, every recycled test mix was still rated good or very good

New research highlights the impressive durability of Swiss highways built with recycled concrete over several decades. The A13 motorway took the lead, using up to 100 percent recycled materials while matching the performance of virgin concrete. While American states are beginning to experiment with recycled aggregates, implementation has not yet matched Switzerland's extent. This successful model could reshape future infrastructure investments in the U.S.
