Paradox: Why the Heaviest Commercial Airplane Remains the Most Pavement Friendly Aircraft at Large Hub Airports

Until the 1990s, flexible airfield pavement design was mainly based on the U.S. Army Corps of Engineers California bearing ratio (CBR) design procedure. The emergence of a new pavement design procedure, the linear-elastic analysis (LEA), which is now widely used, enables a more comprehensive analysis of the effect of an aircraft mix on the pavement structural life. It also provides a tool for airport managers to monitor continuously their pavement and anticipate usual maintenance, and for aircraft landing gear designers to optimize aircraft operations on airfield pavement. This paper discusses how airfield pavements behave when they are subject to an aircraft mix, including new-generation aircraft (777-9, A350-1000), and underlines how the design features of a very large aircraft such as the A380 make it the most pavement friendly aircraft when it is mixed with other wide body aircraft.
