Prefabricated and Lightweight FRP Composite Bridges for Low-disturbance Construction and Road Safety in Sweden

MoRE2020 Fellow Reza Haghani outgoing mobility from Chalmers University of Technology to Colorado School of Mines (USA) and Wayne State University (USA).

Project summary

As the backbone of European transportation systems, the road and railway transport network account for more than 80% of passenger and 50% of goods transport. Bridges, as the most critical elements in transportation networks are the major cause of traffic interruptions and delays, mainly related to their construction and maintenance activities. Traffic delays annually cost 1% of GDP in Europe and, therefore, less disruptive bridge construction methods and more durable bridges, with minimum required maintenance should be developed for improved mobility.

Lightweight and corrosion resistant fiber reinforced polymer (FRP) composite materials, known as contemporary super building materials, are ideal for construction of prefabricated and durable (+100 years) bridge structures. Such bridges need minimum maintenance and have lower life cycle cost compared to traditional steel and concrete bridges. Additionally, FRP bridges are considered to be more sustainable compared to steel and concrete
counterparts as they contain lower embodied energy and result in relatively low carbon footprint during manufacturing, transportation and assembly due to their lightweight. 

The ultimate goal of this project is to create knowledge for design of prefabricated FRP bridges as an innovative solution for nearly zero-intrusive bridge construction, improved mobility, road safety and cost efficiency in Sweden. This project will be an enabler for sustainable urban development in Västra Götaland and contribute in Swedish
carbon-negative vision in 2050. Moreover, it will help Swedish Transport Administration to deal with the challenge of ageing infrastructure and to create resilient transportation networks by developing innovative construction processes using advanced materials.
