Full Depth Recycling has been used in Western Canada since the early 1990's. The use of Expanded Asphalt (Foamed Bitumen) as a Stabilizer in the Full Depth Reclamation process has been used in Eastern Canada since the late 1990's. In 2001, the City of Edmonton, Alberta, contracted with a local contractor and Wirtgen GmbH for the construction of a demonstration project using Foamed Bitumen in the Full Depth Reclamation of three locations. Ellerslie Road consisted of 4 lane-km of a two-lane, low volume, rural section, 70 Avenue consisted of 3.1 lane-km of a two lane, light industrial, rural section and 150 Avenue consisted of 6 lane-km of a four lane, bus route collector roadway. This paper outlines the condition of the pavements prior to rehabilitation, basic design requirements, construction details, testing and evaluation completed and post-construction observations and monitoring of the three demonstration projects.
