| Title | Use of ASTM A1035-CS Uncoated Corrosion Resistant Reinforcement In The Edmonton Valley Line LRT Project |
| Abstract or description | The Valley Line LRT is a 27 km low-floor, urban line that will operate between Mill Woods in southeast Edmonton and Lewis Farms in west Edmonton. The project is being built in 2 stages. Valley Line West The $2.6 billion Valley Line West project is a 14 km light-rail extension from 102 Street downtown to Lewis Farms. It is the second stage of the Valley Line and includes 14 stops and 2 stations.; an urban-style, 27 km LRT line that will operate between Mill Woods in southeast Edmonton and Lewis Farms in west Edmonton. Valley Line Southeast Construction of stage one of the Valley Line Light Rail Transit (LRT) is connecting Mill Woods to downtown Edmonton with about 13.1 km of light rail transit. This stage includes 11 stops, an elevated station incorporating a transit center and Park & Ride, and a transfer point to the existing LRT routes at Churchill Square. The $1.8 billion Valley Line Southeast features new, low-floor, urban-styled trains that will provide more pedestrian-friendly access with at street level stops. And, in residential and commercial areas, embedded tracks will be integrated to the established design and traffic flow of the area. In the design, consistent with practices of Alberta Transportation (AT), ASTM A615 was specified to reinforce concrete structures elements and ASTM A955 for corrosion resistance to chlorides in the exposed elements. During and post the most recent pandemic, materials procurement became a challenge for constructors. ASTM A955 was substituted with ASTM A1035 because of some of its technical and commercial benefits which include: higher tensile to yield ratio for better concrete elements stabilization, superior rebar to concrete bond which minimizes cracks of concrete; no dissimilar metal issues when spliced with either A615 or A955, but equally important the commercial benefit of 20% to 30% lower in cost vs A955, as well as wide availability throughout North America |
| Presentation Description (for Conference App) | This is a technical presentation on the use of A1035-CS uncoated corrosion resistant reinforcement in the Edmonton Valley Line LRT project for sustainable bridge construction. The Valley Line LRT is a 27 km low-floor, urban line that will operate between Mill Woods in southeast Edmonton and Lewis Farms in west Edmonton. The project is being built in 2 stages, the Valley Line West and Valley Line Southeast. ASTM A1035 was used as a substitute to A955 because of some of its technical which include: higher tensile to yield ratio for better concrete elements stabilization, superior rebar to concrete bond which minimizes cracks of concrete; no dissimilar metal issues when spliced with either A615 or A955, but equally important commercial benefit of 30% lower in cost vs A955, as well as wide availability throughout North America |
