The project consisted of the pavement rehabilitation for the 11-mile Cades Cove Loop Road in the Great Smoky Mountain National Park. The project involved the total Full Depth Reclamation (FDR) of the existing roadway sub-base and asphalt paving. FDR was accomplished by the pulverization of the existing asphalt, basestone and portions of the underlying soil subgrade, and the mixing of these materials with the addition of cement and water. Once mixed, the material was spread and compacted under controlled conditions to create a high modulus sub-base for placement of the new asphalt wearing surface. Use of FDR essentially eliminated waste materials and the removal of these through the environmentally-sensitive and often congested Park.
GEOServices provided construction quality control testing and monitoring during the FDR process and asphalt pavement, as well as compaction testing during placement and the making of sample “Pills” for confirmation testing. GEOServices also performed verification coring for post pavement placement.
