ABSTRACT
The article begins by noting the publications used to proceed with the determination of the compositions of flexible pavements.

Then, in detail, explains the procedures used to acquire the inputs needed to develop the project methods.

The following describes the Spreadsheet in which data have been introduced starting and users own aircraft and thicknesses deduced from existing nomograms in two consecutive rules.

Finally, the transformations applied to the basic compositions obtained, to suit the particular conditions available near the airport, in a final table summarizing all the materials used are explained compositions.

Keywords: airport flexible pavement, CBR, MTOW, Configuration landing gear, wheel load, annual departures, ACN of an aircraft, an aeronautical pavement PCN.
