Design Parameters And Associated Quantitative Damage Analyses Of An Asphalt Concrete Airfield Runway

Design parameters and evaluation of associated mechanical behavior of an airfield runway asphalt concrete pavement structure is reported. French aeronautical design methodology was taken as reference. Field and laboratory procedures were employed to determine constituent materials of the designed structure. Stationary linear elastic and dynamic viscoelastic numerical damage analyses were developed and compared, using computerized tools based on 3D Finite Element Methods. Results indicate that viscoelastic analyses provide more discriminating assessment of damage phenomena along the depth of pavement layers, and that landing gear geometric characteristics are more diagnostic than aircraft gross weight for cumulative damage propagation.
