In　present　paper,　the　numerical　simulation　is　conducted　to　investigate　the　dynamic　response　of　the　composited　pavement　system　under　multiple　drop　weight　impact　loads.　This　composited　pavement　system　consists　of　asphalt　concrete　(AC)　layer　reinforced　with　geogrid　(GST),　followed　by　high　strength　concrete　(HSC)　layer,　and　then　engineered　cementitious　composites　(ECC)　layer,　taking　into　account　their　relative　advantages　in　terms　of　strength　and　relative　ductility.　Actual　measurements　from　the　laboratory　test　are　used　as　a　validation　for　the　results　of　the　numerical　simulation.　It　is　shown　that　the　numerical　results　and　laboratory　measurements　from　two　times　of　impact　tests　are　in　great　accordance　in　terms　of　damage　pattern,　crater　diameter,　and　potentiometer　readings.　This　calibrated　model　from　numerical　simulation　could　then　be　further　used　to　investigate　the　factors　that　might　enhance　the　impact　resistance　of　the　composited　pavement　system　subject　to　various　levels　of　impact　loads.　©　2017　American　Society　of　Civil　Engineers.
