The　modified　boiling　test　based　on　image　processing　has　gained　significant　attention　in　recent　years,　aimed　at　replacing　subjective　visual　observation　with　an　objective　measurement.　However,　there　are　still　some　unsolved　problems　influencing　the　accuracy　of　the　test　such　as　the　shadow　between　aggregate　particles　and　the　selection　of　threshold　values　for　binary　image　conversion.　Based　on　these　challenges,　an　innovative　modified　boiling　test　procedure　based　on　digital　imaging　has　been　successfully　developed　for　the　purpose　of　rating　asphalt　mix　ingredients　via　moisture　susceptibility.　The　new　method　focuses　on　a　single　piece　of　aggregate　with　a　newly　cut　smooth　surface,　and　then　the　aggregate　coated　by　asphalt　is　subjected　to　the　boiling　test.　Changes　to　the　thickness　of　the　asphalt　coating　on　the　fresh　surface　before　and　after　boiling　can　be　captured　indirectly　by　digital　images　and　reflected　by　the　changing　average　grayscale　values.　The　experimental　results　of　20　asphalt-aggregate　combinations　clearly　showed　the　moisture　damage　resistance　of　different　samples　and　the　effect　of　liquid　antistripping　agent.　In　addition,　the　test　results　correlated　well　with　energy　ratios　based　on　the　surface　free　energy　measurements　of　asphalt　and　aggregate.　A　decreased　stripping　rate　over　time　were　also　observed　for　all　samples　and　no　significant　stripping　was　found　after　90　min　of　boiling.　The　selection　of　a　suitable　boiling　time　is　critical　to　the　accuracy　of　the　test,　which　can　be　determined　by　trial-and-error　methods.　The　proposed　modified　boiling　test　avoids　the　disadvantages　of　previously　developed　methods　and　provides　a　quick　way　to　evaluate　the　asphalt　mixture　ingredients　by　moisture　susceptibility,　making　it　possible　to　test　a　large　amount　of　samples　within　a　short　period　of　time.　The　new　method　can　be　used　to　generate　an　initial　selection　of　asphalt-aggregate　combinations　in　place　of　the　surface　free　energy　method.
