In　order　to　know　the　working　conditions　of　asphalt　pavement,　sensors　were　installed　in　test　road　and　used　to　track　and　analyze　the　changes　of　working　conditions.　About　3　years　data　related　to　working　conditions　have　been　collected　and　analyzed　till　now.　The　results　showed　that　the　temperature　at　the　bottom　of　top　layer　varies　from　33°C　to　-16.8°C　during　a　year.　The　average　temperature　gradient　in　pavement　is　0.45°C/cm　in　summer　and　-0.1°C/cm　in　winter.　The　results　also　showed　that　the　transverse　strain　on　bottom　of　top　layer　of　pavement　is　between　400-800　μΕ　in　summer,　but　it　is　only　between　60-100　μe　in　winter.　The　compressive　stress　on　top　of　base　course　is　smaller　in　winter　than　that　in　summer.　Some　conclusions　about　the　change　trend　of　working　conditions　is　given　in　the　paper.　©　2016　Taylor　&　Francis　Group,　London.
