Abstract：

The　road　performance　of　Trinidad　Lake　Asphalt　(TLA)　modified　petroleum　asphalt　(PA)　were　evaluated.　Results　show　that　TLA　improves　the　high　temperature　performance　of　PA　to　avoid　rutting　resistance,　while　it　degrades　the　low　temperature　performance　of　PA　making　PA　face　more　risk　of　cracking.　Meanwhile,　the　influence　of　TLA　on　short-term　aging　performance　of　PA　is　slight,　but　TLA　enhances　the　long-term　aging　(PAV　and　UV)　resistance,　which　is　favorable　for　extending　lifetime　of　pavement.　According　to　this　investigation,　TLA　modified　asphalt　is　recommended　to　be　used　in　warm　areas　and　the　optimal　addition　of　TLA　is　30 wt.%　for　the　road　construction.　©　2017　Taylor　&　Francis　Group,　LLC.
