Expansion joints are a nightmare in the maintenance of highway bridges. After a few decades, the junction points between the structure and the road begin to show signs of deterioration. Scientists at EPFL are attempting to do away with this costly technique, and have set up a life-size experiment on the campus. Switzerland is a […]
