Alverca Airfield Pavements Strengthening and Overlay, Widening and Requalifying for “Wide-Body” Aircraft
On the first of July of 1995 the “Grupo de Engenharia de Aerodromos da Força Aerea Portuguesa-GEAFA” conducted a bearing capacity evaluation campaign with static plate bearing tests to evaluate the load classification number (LCN) on the runways and taxiways of the Alverca Airfield. A LCN value of 14 was achieved for the runway, taxiways and apron pavements. With this 14 LCN value the Aeronautical Infrastructure has become very restrictive for use by mission and current aircraft. In order to avoid operation aircraft restrictions, it was necessary to overlay the airfield pavements, and also, to widen and requalify them for “wide-body” aircraft, in accordance with the Annex 14- Aerodromes by the International Civil Aviation Organization (ICAO), This paper describes several design and evaluation methods used for pavements strengthening: the LCN Method; the California bearing ration (CBR); and the method used by the USA Corps of Engineers). At the end of the pavement overlay design process, the overlay thickness results were evaluated by the Aircraft Classification Number (ACN); Pavement Classification Number (PCN); and the method of ICAO.
