Comparing Rigid and Flexible Airport Pavement Thicknesses Designed by Different Methods

Rigid and flexible aircraft pavement were designed using the software FAARFIELD v1.4, FAARFIELD v1.3, COMFAA (rigid only), and APSDS (flexible only). The designs included a range of subgrade conditions, as well as commercial aircraft with two, four, and six wheeled landing gear. Comparison of the results indicated that FAARFIELD v1.4 returns flexible pavement sub-base thicknesses 20% less than FAARFIELD v1.3, but 13% greater than APSDS. FAARFIELD v1.4 also returned rigid pavement concrete thicknesses that were generally less than FAARFIELD v1.3 and COMFAA, except for the six wheeled gear. It is recommended that further research consider whether the significant increase in rigid pavement thickness associated with the six wheeled landing gear applies to other aircraft with similar wheel configurations and whether the increased rigid pavement thicknesses for six wheeled landing gear, compared to FAARFIELD v1.3, are justified.
