A　new　type　of　epoxy　resin　adhesive　was　prepared　by　mixing　ratio　tests,　which　can　apply　in　the　ultra-thin　pavement　with　the　high　flexibility　and　bond　strength.　The　effects　of　toughening　agents,　diluents　and　curing　agents　with　different　types　and　dosages　on　the　tensile　properties　of　adhesives　were　evaluated　by　tensile　tests.　Afterwards,　the　scanning　electron　microscope　(SEM)　and　Fourier　transform　infrared　spectroscopy　(FTIR)　were　used　to　investigate　the　mechanism　of　various　additives.　According　to　the　strength　test,　the　optimum　mixture　ratio　composition　A　(epoxy　resin　and　modifiers)　is　that　epoxy　resin　E-51:　epoxy　resin　E-44:　toughening　agent　F-1:　diluent　D-1:　fire　retardant　=　50:50:20:10:8;　the　component　B　(curing　agent　and　modifiers)　is　that　curing　agent　H1:accelerator:coupling　agent　=　70:10:2.　Meanwhile,　the　effect　of　toughening　and　interpenetrating　was　realised　through　the　network　formed,　which　caused　by　the　intertwining　of　polyurethane　(F-1)　and　epoxy　resin　in　the　mixed　system;　the　diluents　improved　ductility　by　reducing　the　crosslinking　density　of　adhesives;　the　amino　group　in　the　curing　agent　reacted　with　the　epoxy　group.　While　the　phenomenon　of　agglomeration　within　the　paving　material　was　caused　by　the　excess　number　of　adhesives,　that　resulting　in　a　low　reaction　speed　and　slow　strength　formation.　And　then　the　colloidal　stone　ratio　was　determined　to　be　1:4.
