Based　on　field　tests　and　numerical　simulation　methods,　distribution　characteristics　of　early-age　built-in　temperature　of　cement　concrete　pavement　constructed　in　different　seasons　and　pouring　time　were　analyzed　firstly.　Then　considering　effect　of　creep,　characteristics　of　early-age　zero　stress　temperature　in　cement　concrete　that　built-in　temperature　of　cement　concrete　pavement　constructed　in　different　seasons　and　pouring　time　has　a　great　difference.　The　distributions　of　built-in　temperature　along　the　thickness　present　nonlinear　obviously,　and　they　have　four　typical　types:　concave　and　positive　gradient　type,　concave　negative　gradient　type,　convex　positive　gradient　type　and　convex　negative　gradient　type.　Zero　stress　temperature　gradient　shows　prominently　developing　process　compared　with　built-in　temperature　of　slab　at　different　ages　by　the　effect　of　creep.　Zero　stress　temperature　of　slab　poured　on　am7:00　in　summer　firstly　increase　and　then　decline.　Besides,　the　positive　gradient　change　to　negative　gradient　gradually,　and　the　gradient　of　zero　stress　temperature　trend　to　decrease.　At　last,　it　is　recommended　to　calculate　zero　stress　temperature　of　slab　consideration　of　base　temperature　and　the　nonlinear　distributions　characteristics,　and　the　combined　effect　of　creep　and　age.
