| Zusammenfassung: | <jats:p>Airfield pavements are designed to handle an increasing volume of conventional aircraft, but in the future they may be required to accommodate both unmanned aircraft and space vehicles; these have their own unique requirements in terms of pavement strength and durability.This study deals with the problem of application of loads on the runway during landing. The solution of this problem, necessary for the correct construction of the decay curve, has been studied with reference to the Grip Number (GN). The experiment has been conducted on the runway of the Airport of Lamezia Terme ( IATA: SUF, ICAO: LICA) - Italy. Traffic data (from 2010 to 2014) and data on surface features (in terms of GN) for the same period (according to the Publication-ICAO Doc.9137-AN / 898, where guidelines Speed equals 65 km / h) were acquired for the goals of this study.The analysis of the data has supplied important information about the conditions of application of the loads on the Runway. In particular, through an optimization procedure and the use of the technique OLS, a relationship of application of loads on the runway has been proposed and furthermore two different areas, in reference to the methods of the application of loads in the process of landing, have been defined: a first part x1 within which the load is applied gradually with a linear law, and a second part (L-x1), in which all the load is applied with a constant law.</jats:p> |
