Cold climates, frequent salting, and heavy use threaten the reliability of the transportation infrastructure we rely on every day. And with municipalities responsible for covering 60 per cent of their costs, coming up with the funds necessary each year to replace and expand essential infrastructure is an ongoing challenge. As such, finding cost-effective, efficient methods for monitoring and rehabilitating existing infrastructure has become vitally important.
South of the border, a large amount of resources have been invested into researching non-traditional methods for infrastructure evaluation and preventative maintenance.
The U.S. Transportation Research Board launched a study known as the Strategic Highway Research Program (SHRP2) that evaluates the effectiveness of applying various non-destructive techniques, such as ground penetrating radar (GPR), impact echo, ultrasonic surface waves, and electrical resistivity, among others, to capture subsurface data on corrosion, delamination, vertical cracking, and concrete degradation.
The report concluded that rapid, non-destructive condition assessment significantly reduces the overall resources and expenditures required for bridge renewal. Kevin Vine, President of multiVIEW, discusses the topic in the latest issue of ReNew Canada Magazine.
