Introduction: Airportpavementsaredesignedtowithstandtheweightofaircraftandthestressinducedbylanding,takeoff,andtaxiingoperations.Overtime,however,thesepavementsmayundergodistresses,suchascracking,rutting,anddisplacement.Pavementdisplacement,orfaulting,occurswhensectionsofthepavementsubsideorheave,leadingtounevensurfacesandpotentialhazardsforaircraftoperations.
