The　cost　of　Highway　semi-rigid　base　asphalt　pavement　construction　is　so　high　and　the　quality　problem　impacts　the　service　performance　of　pavement　structure　and　the　service　level　of　the　road　directly,　so　researches　on　the　methods　of　controlling　pavement　cracks　and　other　diseases　are　always　hot　fields　of　road　engineering　and　academic　circles.　It　is　known　that　the　early　damage　of　Highway　semi-rigid　base　asphalt　pavement　is　inevitable,　the　existing　methods　are　on　some　degree　efficient　on　delaying　the　formation　and　extension　of　cracks,　but　the　effect　is　limited　with　different　methods　and　various　mechanisms　of　preventing　cracks.　Base　on　force　analysis　of　pavement,　this　article　presents　a　new　technology　of　crack　controlling　which　uses　intelligent　composite　materials　interlayer.　By　adding　a　stress　absorbing　layer　between　the　asphalt　surface　layers　or　the　semi-rigid　base　layers　with　low　modulus,　good　toughness,　self-adaptability　and　self-control　ability,　the　intelligent　composite　materials　interlayer　has　a　good　effect　on　controlling　cracks　which　has　been　proved　by　the　theoretical　calculations　and　experimental　analysis.　As　a　result,　the　intelligent　composite　materials　interlayer　could　efficiently　prevent　and　delay　the　formation　and　extension　of　cracks,　the　safety　and　comfort　of　highway　could　be　improved　significantly　while　the　cost　of　construction　and　maintenance　decreasing.　And　the　service　level　and　social　image　of　the　road　could　also　be　improved　effectively.　This　research　has　important　academic　and　application　value.
