BASIC AIRFIELD INFORMATION
2-1. Basic airfield data. A considerable amount of basic airfield data is incorporated into the condition survey report.
Most of this information is contained in construction and maintenance records and in previous condition survey reports.
2-2. Desired data. The following items should be compiled for subsequent use during the condition survey:
a. Design/construction/maintenance history. The history of maintenance, repair, and reconstruction from original
construction of the pavement system to the present.
b. Traffic history. Aircraft traffic records, including aircraft type, typical gross loads, frequency of operation, percent
runway usage, and taxiway and apron usage should be available.
c. Climatological data. Annual temperature ranges and precipitation data.
d. Airfield layout. Plans and cross sections of all major pavement components, including subsurface drainage
systems should be available. These should be updated to reflect new construction upon completion of the project. In
addition, known subsurface geologic data, especially ground water presence and direction of flow should be shown.
Longitudinal and transverse grades should be indicated on runway and taxiway profile and cross-section drawings.
e. Frost action. If applicable, records of pavement behavior during freezing periods and subsequent thaws should be
f. Photographs. Photographs depicting both general and specific pavement conditions should be taken.
g. Pavement condition survey reports. All previous pavement condition survey reports should be maintained to be
referenced in the current report.
