ACES Completes Pavement Study for Queen Ali International Airport in Jordan

The materials Department at ACES Amman in cooperation with ACES Regional Center of Excellence for Pavement Studies & Evaluation has completed a Pavement Structural Evaluation Study for the Northern Runway at Queen Alia International Airport. The study included nondestructive evaluation using the heavy falling weight deflectometer and surface texture and roughness measurement, and destructive testing through obtaining cores from the asphalt and concrete pavements, dynamic cone penetrometer (DCP) survey and excavation and evaluation of asphalt and soil test pits.  The available Super Heavy Falling Weight Deflectometer (SH-FWD) at ACES was used to perform the deflection testing at 430 test locations along the runway.  To represent Boeing B777-300 aircraft wheel load, each test location was evaluated by applying a load pulse of 27.0 tons and the resulting deflection basin was measured through the use of fifteen geophones. Through the use of the back-calculation techniques, moduli of all pavement layers were calculated and the Pavement Classification Numbers (PCN) of the runway were obtained.  Three dimensional drawings for the PCN, surface roughness and surface texture distribution along the airport runway were submitted to the client (Ministry of Public Works and Housing).
