Sensitivity analysis of aircraft parameters on functional pavement design is the primary goal of the MLGPAV program at the Transportation Computer Center (TCC) in Washington, D.C. The program is an integrated system which is data independent based on defined mathematical models and operational logic. The input data is divided into job and universal default inputs. The job inputs consists of only the aircraft data such as: 1) forecast of aircraft movements; 2) maximum takeoff weight; 3) natural frequency of aircraft at tire pavement interface; 4) tire pressure of main landing gear wheel; 5) wheel configuration of main landing gear and 6) gear spacing. The default system contains all of the data independent of the aircraft, such as: 1) regional cost values; 2) types of facility, runway, taxiway, apron: 3) navigation system; 4) operation speed; 5) roughness and maintenance standards; 6) subgrade conditions and 7) airport traffic distribution. A unified mechanistic method is used to design five types of functional pavements for identical service requirements on riding quality and maintenance needs. They are: 1) asphalt pavements in southern or northern region; 2) concrete pavements on stabilized or aggregate base and 3) full depth stabilizd base pavement. The MLGPAV program operation involves extensive use of data storage and filing techniques. The current operational program and this manual are prepared for execution on the computer hardware system at TCC. (Author)
