Clay County, Kentucky
The project includes a new high school building and asphaltic concrete paving.
The site is a previously undeveloped site in the Eastern Kentucky coal fields on top of a ridge with moderate to steep slopes to the valley floor.
The pavement experienced rutting, alligator cracking, and general failure during the first year of service.
Site grading during the construction included cuts of about 20 feet. These cuts extended below the stabilized water table, and seepage from the cut slope entered the pavement subgrade. In addition, cores taken through the pavement and base courses on a 50 foot grid revealed that over half of the constructed pavement did not satisfy the minimum design requirements.
The owner and the general contractor negotiated a settlement that included reconstruction of large portions of the failed pavement and overlayment of the remainder to bring the existing conditions into compliance with the design. The general contractor and his paving subcontractor submitted their dispute to arbitration about the cost of repairs and the allocation of responsibility.
