LID Permeable Paving

GTAA Toronto Airport

Ecoraster® E50 was installed by the Greater Toronto Airport Authority (GTAA) as soft shoulder reinforcement in order to stabilize the asphalt edge and reduce the regular maintenance needed on the soft shoulder. Soft shoulder reinforcement using Ecoraster® is a regular application throughout Europe. It was installed as a pilot area by the GTAA to monitor the reduction in maintenance needed with Ecoraster® support as opposed to the regular maintenance needed on both the gravel soft shoulder and the asphalt edge of the road.

Ecoraster® was installed after the asphalt surface and then filled with gravel. The area can be snow plowed and provided the first level of infiltration for all run off from the road. This directly reduced the environmental impact of the pollutants on the roadside vegetation.
