Innovative Pavement Engineering & Life-Cycle Advisory for High-Priority Winnipeg, Canada Transitway
The Transtec Group, Austin-based pavement engineering firm, Texas, USA, provided pavement design and life- cycle advisement to Plenary Roads-Winnipeg—the concessionaire for the Southwest Rapid Transitway (Stage 2) project in Winnipeg, Manitoba, Canada. According to the City of Winnipeg, the Southwest Rapid Transitway has been designated as one of the highest-priority projects as part of the Transportation Master Plan to address projected population growth. The completed transitway will connect downtown with the Southwest sector and the University of Manitoba, and will allow city transit to bypass heavy traffic on Pembina Highway.
The Transtec Group served as the pavement life cycle advisor on Stage 2 of the project, which includes a 7.6 km exclusive transitway constructed within dedicated rights of way. Because of the cold climate in Winnipeg, the ground is subject to significant freeze-thaw cycles, causing pavement profile deformation. Transtec provided guidance in the operations and maintenance strategy. “We had to be very meticulous in our evaluation to ensure the material selection and maintenance plan for the roadway will hold up to the elements,” said Dan Dawood, Director of Business Development & Engineering-The Transtec Group.
“Typical assessments may have over-estimated the maintenance needed, leading to higher costs and a less-than-optimal maintenance and operations strategy. Our experience with creative thinking, in regards to pavement design, means we used data to help determine the optimal diamond grinding frequency needed to achieve the desired pavement surface profile to save budget while ensuring safety and longevity.”
Transtec evaluated northern U.S. states and other Canadian provinces to assist the concessionaire in finding competitive pricing for operations and maintenance strategies. Transtec also recommended enhanced joint and drainage design to mitigate the effects of low temperatures within the base foundation structure. In addition, Transtec provided recommendations and a separate verification process to ensure an optimized pavement design.
In addition to design and life cycle costing, the firm analyzed risk and created a 30-year maintenance plan for Plenary Roads Winnipeg that met final handback requirements for a safe, long-lasting transitway. The project is a public-private-partnership (P3), and received joint public funding from the P3 Canada Fund, the Province of Manitoba, and the City of Winnipeg. Construction began in late summer 2016, with expected completion in late 2019.
