This　paper　presents　the　details　of　the　laboratory　performance　evaluation　of　the　three　types　of　polymer　modified　binders　and　their　respective　porous　asphalt　concrete.　The　same　gradation　was　applied　to　all　the　mixtures　and　the　base　bitumen　was　Shell　60/70.　The　binder　test　results　indicate　that　the　SBR　and　SBS　modified　binders　have　the　smaller　temperature　susceptibility　and　exhibit　better　performance　in　resisting　ageing,　rutting,　and　fatigue　than　the　conventional　penetration　60/70　binder.　When　evaluated　in　a　series　of　laboratory　tests　designed　to　assess　the　fundamental　mechanical　properties　and　durability　performance　of　porous　asphalt　concrete,　the　results　show　that　the　SBS　modified　porous　asphalt　concrete　exhibit　the　most　overall　satisfactory　performance　with　respect　to　stiffness,　dynamic　creep　deformation,　rutting,　and　moisture　resistance　damage　among　the　three　types　of　porous　asphalt　concretes　studied.　Based　on　the　lab　results　and　the　cost-effectiveness　analysis,　the　SBS　modified　porous　asphalt　concrete　is　recommended　as　the　most　favorable　material　to　be　used　as　a　friction　course　in　Hong　Kong.　©　2009　ASCE.
