IN-2: Innovation 2

The Green Street Pilot Project The "Green Street Pilot Project" was a partnership between Facilities Management and the Saskatchewan Centre of Excellence for Transportation and Infrastructure to reconstruct a road in manner which limited greenhouse gas emissions, improved city transit access and took advantage of onsite salvaged construction demolition materials. The condition of the North Road had fallen into near failure due to the heavy transit traffic. It was reconstructed using salvaged materials like construction rubble, crushed concrete, glass, and porcelain. While road construction from construction rubble is common in warmer climates, it is not well known in this part of the world. This project provides an opportunity to assess the performance of this approach to road construction in extremem climatic conditions. It is anticipated that the approach will produce a more durable finished product that will also provide one solution to the issue of costruction, renovation and demolition waste disposal. Other portions of the road are being used to test a variety of paving techniques. In one portion of the road asphalt was applied using a cold process (much less energy-intensive), reducing the greenhouse gas emissions associated with the construction phase of the project. In another section a form of pervious pavement was installed, allowing us to test the applicability of the product to our extreme weather conditions. The road performance is being monitored and it is hoped that these techniques will help transform the local road re-building industry by lowering capital and lifecycle costs, lowering emissions, enhancing road performance and providing useful end-uses for recycled construction, renovation, and deconstruction waste. http://www.usask.ca/communications/ocn/09-may-08/greencampus.php http://www.usask.ca/communications/ocn/09-sept-04/9.php
