This project consisted of a comprehensive study and implementation of an Infrastructure Investment Plan at JFK International Airport for Delta Air Lines Terminal 2. Delta Air Lines plans to increase flights and also invest more than $300 million in improving its JFK terminals over the next six years. The facility investments planned for Terminal 2 focused on the scope of work required to maintain operational reliability, improve service levels and address building code deficiencies. The project scope included passenger experience enhancements, infrastructure improvements to building systems, envelope and apron pavement rehabilitation. During the study phase, DY’s involvement included a study of the existing airside pavement and proposal for rehabilitation.
The apron/taxilane pavement consisted of bituminous asphalt pavement and Portland Cement Concrete (PCC) pavement. In order to provide an objective and standardized description of the functional pavement conditions for the apron/taxilane, a Pavement Condition Index (PCI) survey was performed. Testing and structural analysis of the pavement conducted along with both destructive and nondestructive testing (NDT) procedures. The data obtained included pavement thickness, composition, and pavement strength. The data was considered along with the current and forecasted air traffic during the engineering analysis in order to make specific recommendations concerning pavement rehabilitation and to validate whether the pavements were structurally adequate.
The following recommendations were made:
- Salvage the majority of the airside concrete ramp area. Preliminary investigations determined repair actions for each specific distress. The repairs varied from a simple crack repair to an extensive slab replacement program.
- The existing airside bituminous pavement was no longer structurally or functionally acceptable.The suggested repair was to mill and remove the existing pavement section and replace it with a new pavement section.
The project was divided into phases. As part of this phase of construction, work was confined to the concrete and asphalt pavement to the south of Terminal 2 only. During this phase of construction only shattered concrete slabs were replaced with the new pavement section in the concrete apron. Also as part of this phase, asphalt pavement to the south of Terminal 2 and extending to the centerline of the taxilanes between Terminals 1 and 2 was rehabilitated.
This work involved milling the existing pavement and replacing with new bituminous pavement. Some areas required a full pavement reconstruction. The cost of this work was approximately $15 million.
