In　order　to　improve　the　overall　performance　of　antifreeze　asphalt　pavement,　the　selection　and　the　optimal　mix　ratio　of　carrier　in　antifreeze　materials　were　studied.　The　storage　performance　and　slowrelease　performance　of　different　carriers　for　the　deicing　chemicals　were　compared　by　specific　surface　area　test,　conductivity　test　and　scanning　electronic　microscope(SEM).　Based　on　the　torsion　test,　the　conductivity　test　and　the　freezethaw　splitting　test,　the　antifreeze　performance　and　road　performance　of　antifreeze　material　with　different　ratios　of　deicing　chemicals　to　carriers　were　evaluated.　The　results　demonstrate　that　most　of　the　deicing　chemical　is　adsorbed　on　the　surface　of　the　carrier,　and　only　a　small　portion　is　stored　in　the　pores　of　the　carrier.　Further,　the　carrier　itself　has　little　effect　on　the　slowrelease　performance　of　antifreeze　materials,　incorporating　surface　modifiers　can　effectively　alter　the　slowrelease　performance　of　antifreeze　material.　The　larger　the　ratio　of　deicing　chemical　to　carriers　in　the　antifreeze　material,　the　better　the　snow　melting　performance　is　to　a　certain　extent,　but　the　worse　the　water　stability　is.　There　is　an　optimal　mix　ratio　of　deicing　chemical　to　carrier,　which　can　ensure　the　stability　of　antifreeze　performance　and　road　performance　at　the　same　time.　©　2022,　Editorial　Department　of　Journal　of　Building　Materials.　All　right　reserved.
