FOREIGN EXPERIENCE IN THE USE OF GEOSYNTHETICS IN AIRFIELD PAVEMENTS: A SCIENTIFIC AND ANALYTICAL APPROACH

Abstract

The article systematically analyzes the experience of the United States, Europe, and Asian countries in the application of geosynthetic materials in airfield pavements. Based on FAA and ICAO documents, scientific journal papers, and conference proceedings on airfield pavements, the separating, reinforcing, drainage, and crack-mitigation functions of geotextiles, geogrids, geocells, and geocomposites are discussed [1-5]. The evaluation criteria used in foreign studies are generalized, and analytical relationships associated with the Traffic Benefit Ratio, deformation moduli, and life-cycle costs are presented [4, 6, 7, 11]. It is noted that the Polish case of strengthening a natural airfield pavement with a geogrid system improved load-bearing capacity by approximately 30%, while full-scale FAA tests showed pronounced differences in TBR values among various geosynthetics [4, 7]. Based on this international experience, practical recommendations are formulated for the airfield infrastructure of Uzbekistan.
