Abstract
In North America, there is a persistent problem of the deterioration of steel-reinforced concrete which has limited the service life and increased the maintenance cost of such structures. The first Canadian continuous reinforced concrete pavement (CRCP) built on a highway was constructed in 2000 in the province of Quebec. Some cores taken in the first CRCP section five years after construction were already showing some corrosion in the longitudinal reinforcement at the crack location. Many options were then analysed in 2005 to resolve this problem and galvanised steel was selected as reinforcement for the next projects. One other non-corrosive reinforcement alternative is glass fibre reinforced polymer (GFRP). Fifteen (15) slab sections over an area of 150 m in three-lanes of Highway 40 Eastbound in Montreal (Quebec) were constructed using the newly developed CRCP system with GFRP reinforcement. In addition, 3 slab sections were reinforced using steel bars for comparison purposes. The main objective of this research project is to implement the technology and design of GFRP reinforcing bars in order to demonstrate their ability to meet all CRCP requirements.
