The　properties　of　Trinidad　Lake　Asphalt　(TLA)　and　SBS　compound　modified　petroleum　asphalt　were　investigated.　Results　show　that　the　compound　of　TLA　and　SBS　exhibits　a　remarkable　combined　effect　on　enhancing　the　deformation　resistance　of　asphalt,　and　SBS　can　offset　partial　negative　effect　of　TLA　on　the　creaking　resistance　of　asphalt,　which　will　extend　the　applicable　area　of　TLAMPA.　FTIR　and　TG　curves　indicate　TLA　and　SBS　are　physically　mixed　into　petroleum　asphalt　and　have　little　influence　on　the　thermal　stability.　TLA　and　SBS　also　exhibit　combined　effect　on　improving　anti-aging　performance　of　asphalt,　which　would　extend　the　service　life　of　pavement.
