Recycling Award for Toledo
The City of Toledo has won a 2012 Roads & Bridges Magazine Recycling Award. This national award in the Full Depth Reclamation Category is given to one project per year, and is co-sponsored by the Asphalt Recycling and Reclaiming Association.
The winning project is Toledo’s 2012 Full Depth Reclamation that included residential streets in the old South End, west Toledo, and Point Place. The process improved approximately 3.5 miles of streets for a little over $2.4 million. The project team included Soils and Materials Engineers, Inc. which performed the pavement mix design, and Tenmile Creek Excavating which performed the full depth reclamation.
Full Depth Reclamation (FDR) is a process that reuses existing road materials to form the base for the new roadway. This base is then topped with 3 to 4 inches of new asphalt. As its name indicates, it is a full depth treatment that is done in-place with very little material being hauled away to a landfill. What allows the existing road material to be reused effectively is the addition of a binding agent that is mixed with the road material to create a very strong base.
Compared to Full Reconstruction, FDR offers significant cost and time savings. Toledo has been using it since 2010 and has seen an average savings of about 55% over a traditional Reconstruction. The construction time and inconvenience to residents is also significantly reduced.
