Glass fibre reinforcement in bridge structures

For the last 20 years, glass fibre reinforcing bars were developed for installation as reinforcement in the concrete decks of bridges in North America, where the intense use of de-icing salts had led to severe degradation of steel reinforced bridge decks. Two recent research projects focussed on this strength of newest generation glass fibre reinforcing bars. The first studied their behaviour in concrete bridge barrier walls as they are commonly built in the United States and in Canada. This project culminated in a full-scale crash test on a TL-5 (highest load level barrier wall according to the AASHTO Manual for Assessing Safety Hardware (MASH)) using a 36 tonne tractor trailer hitting the wall at a speed of 80 km/h. In the second project the benefits of installing non corroding dowels to connect two different loaded members were assessed.
