BACKGROUND:
The aircraft parking apron/ramp directly in front of the General Aviation Terminal is about 140,000 square feet and rates 52 (poor) on the Pavement Condition Index (PCI). The current pavement section is 8.5" of asphalt over a 12" lime rock base supported by 12" of a clay-stabilized subgrade. The base and first few layers of asphalt are some of the oldest on the airport, original to the airport's construction in the late 1960s. In 2008, after water infiltration through the subgrade dislodged dinner plate-sized sections, the top 2" of asphalt was replaced. At the time, funding was not available to correct the underlying problems.
Today, problems exist with asphalt rutting, possibly the result of a subgrade failure or a poorly constructed bituminous surface mix.
This Federal Aviation Administration (FAA) grant funds the design of the rehabilitation of this ramp area. The existing pavement section will be load-tested with a heavy-weight deflectometer to determine strength. Pavement cores shall extend into the subgrade to ensure the base's adequacy. Initial considerations are to mill the asphalt to a 5-7" depth and replace it with a similar thickness of Portland Cement Concrete (P-501). Depending on the results of the testing, deeper rehabilitation may be required. Construction will occur in Calendar Year 2025 and be funded through a separate, future FAA (and possibly FDOT) grant.
The design will be conducted...
