This　paper　studies　the　modification　of　petroleum　asphalt　with　enzymatic　hydrolysis　lignin　(EHL)　epoxy　resin.　EHL　epoxy　resin　was　successfully　synthesized　by　EHL,　a　novel　eco-material　with　high　chemical　reactivity.　Different　amounts　of　EHL　epoxy　resin　were　compounded　into　AH-70　paving　asphalt.　The　effect　of　EHL　epoxy　resin　on　modified　asphalt　was　examined　by　penetration,　soften　point,　thin　film　oven　test　(TFOT),　ductilily　tests.　The　results　showed　that　EHL　epoxy　resin　had　marked　effect　on　the　high-temperatrue　property　of　increasing　softening　point　at　the　content　of　2-9wt%　and　it　had　significantly　effect　on　the　low-temperature　properties　and　aging　resistance　with　EHL　epoxy　resin　content　of　2-9wt%　in　modified　asphalts.　TG　analysis　indicated　that　EHL　epoxy　resin　had　the　high　mass　loss　temperature　than　pure　asphalt.　Anti-aging　property　of　asphalt　was　improved　by　compounding　EHL　epoxy　resin　with　asphalt.　©　(2011)　Trans　Tech　Publications.
