In　order　to　solve　the　problem　of　the　application　of　reclaimed　asphalt　pavement　(RAP)　in　unbound　granular　materials,　an　investigation　into　the　effect　of　RAP　on　the　performance　of　coarse　graded　unbound　granular　materials　was　conducted.　A　series　of　laboratory　tests　used　UTM-100　including　the　repeated　load　triaxial　test,　the　quick　shear　test　and　the　permanent　deformation　test　were　performed　on　coarse　graded　UGMs　containing　RAP　as　well　as　UGMs　of　neat　virgin　aggregates　at　room　temperature(22℃).The　effect　of　RAP　on　the　performance　of　unbound　granular　materials　was　analyzed　in　accordance　with　the　experimental　results.The　test　results　show　that　after　adding　RAP,　the　dynamic　resilient　modulus　of　coarse　graded　unbound　granular　materials　increase　obviously,　and　the　average　growing　rate　is　9.3%.　The　growing　rate　is　affected　by　confining　pressure　and　the　ratio　of　bias　to　confining　pressure.　And　the　ratio　of　bias　to　confining　pressure　has　more　significant　influence.　The　shear　strength　decrease　and　the　decreasing　rapid　is　slower　in　stress　softening　stage.　When　shear　failure　occurs,　coarse　graded　unbound　granular　materials　have　similar　dilatancy　effect.　Axial　permanent　deformation　increases　distinctly,　which　shows　material＇s　resistance　to　permanent　deformation　declined.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
