Full-depth reclamation involves roto-tilling the existing pavement into the underlying surface to create a new base for paving. This process was also used to repave the roads in the Cosby Campground as shown above.
During the spring of 2010, the Cades Cove Loop Road was repaved. The "full-depth reclamation" process involved in rehabilitating the 11-mile long road used specialized equipment that essentially roto-tilled the existing pavement, mixed it with the underlying materials to a depth of six inches, then incorporated water and Portland cement. The resulting base was allowed to harden for 5-7 days before repaving.
The construction method selected eliminated the time, pollution and cost of milling of the old pavement and trucking hundreds of loads of it back to the asphalt plant for reprocessing. Instead the pavement was recycled in place, so it was a much more environmentally responsible way of getting the work done.
