The　influence　of　the　chemical　composition　of　asphalt,　the　aggregate　lithology,　and　the　morphological　characteristics　of　the　aggregate　on　the　level　of　adhesion　between　the　asphalt　and　the　aggregate　is　investigated.　A　contactless　three-dimensional　(3D)　white-light　scanning　technique　is　used　to　obtain　point　cloud　data　of　the　aggregate　particles.　Six　independent　feature　parameters　are　used　as　evaluation　indices　to　quantitatively　describe　the　multilevel　features　of　the　3D　morphology　of　road　aggregates.　Methods　for　analyzing　the　feature　parameters　based　on　the　point　cloud　data　of　the　aggregate　are　presented.　Subsequently,　the　process　and　evaluation　standard　of　the　adhesion　test　are　improved　to　quantify　the　spalling　degree　of　the　asphalt　film　on　the　aggregate　surface　under　boiling　conditions.　The　influences　of　the　chemical　composition　of　the　asphalt　and　the　aggregate　morphology　on　the　level　of　adhesion　between　the　asphalt　and　aggregate　are　analyzed,　and　the　compatibility　between　aggregates　with　different　lithologies　and　the　asphalt　is　assessed.　The　results　show　that　the　shape　factor　(SF)　can　be　used　to　characterize　the　needle-flake　shape　of　the　particles,　the　ellipsoid　index　(E)　is　suitable　to　determine　the　angularity　of　the　aggregate　particles,　and　the　3D　joint　roughness　coefficient　(JRC(3D))　describes　the　roughness　of　the　particle　surface.　The　type　of　adhesion　between　the　aggregate　and　the　asphalt　includes　chemical　and　physical　adsorption;　chemical　bonding　is　relatively　strong,　and　the　physical　orientation　force　and　mechanical　interlocking　force　are　relatively　weak.　Alkaline　limestone　aggregates　should　be　used　with　asphalt　with　a　high　aggregate　content　of　colloid　and　asphaltenes.　Basalt　aggregate　with　weak　alkalinity　should　be　used　with　asphalt　with　a　high　colloid　content,　and　the　use　of　angular　aggregates　should　be　avoided.　Acidic　aggregates　with　compact　shapes,　few　edges　and　corners,　and　rough　surfaces　should　be　used　prudently.
