To　explore　the　dynamic　properties　of　asphalt　concrete　under　severe　dynamic　loading,　the　apparatus　of　servo　hydraulic　machine　and　split　Hopkinson　pressure　bar　(SHPB)　were　employed　to　conduct　the　dynamic　compression　test　for　asphalt　concrete　material.　The　dynamic　increase　factor　(DIF)　and　dynamic　stress-strain　curve　were　then　obtained　for　asphalt　concrete　under　middle　to　high　strain　rates.　At　same　time,　the　advanced　elasto-plastic　damaged　model　strain　rate　effect　was　used　to　simulate　the　dynamic　behavior　of　asphalt　concrete　in　SHPB　test.　The　key　parameters　for　the　selected　material　models,　i.e.　parameters　of　strength　surfaces　and　the　damage　factor,　were　calibrated　and　quantified　through　laboratory　tests.　The　results　obtained　are　stated　as　follows:　the　apparatus　of　hydraulic　servo　machine　and　SHPB　can　be　effectively　used　to　obtain　the　DIF　curve　for　asphalt　concrete　under　middle　to　high　strain　rates.　The　compressive　strength　of　asphalt　concrete　increased　with　the　enhancement　of　strain　rates.　Laboratory　tests　can　be　used　to　quickly　determine　the　key　parameters　of　advanced　elasto-plastic　damaged　model　in　order　to　represent　the　dynamic　stress　strain　behavior　of　asphalt　concrete.　It　was　also　found　that　the　compressive　DIFs　of　asphalt　concrete　obtained　from　SHPB　test　should　consider　contribution　from　two　factors,　one　was　the　moisture　effect　at　lower　stain　rates　which　was　related　to　the　first　branch　of　DIFs　curve　obtained　from　SHPB　test,　and　another　was　the　lateral　inertial　confinement　effect　at　higher　stain　rates　which　was　related　to　the　second　branch　of　DIFs　curve　obtained　from　SHPB　test.　However,　for　the　numerical　model　of　asphalt　concrete　under　dynamic　loading,　adopting　the　DIFs　curve　obtained　from　SHPB　test　would　duplicate　the　inertial　effects.　Hence,　when　the　numerical　simulation　of　asphalt　concrete　under　high　strain　rate　loading　was　conducted,　the　second　phase　of　compressive　DIF　obtained　from　SHPB　test　should　not　be　considered,　that　is,　the　compressive　DIFs　obtained　from　SHPB　test　should　be　modified.　©　2017,　Editorial　Board　of　Journal　of　Tianjin　University(Science　and　Technology).　All　right　reserved.
