Based　on　the　climate　parameters　of　five　Chinese　regions,　the　distributional　characteristics　of　built-in　temperatures　of　cement　concrete　pavements　in　different　regions　with　different　altitudes　and　latitudes　were　studied　by　using　the　computational　program　of　early-age　temperature　field　of　cement　concrete　pavement.　The　superposition　effect　of　built-in　temperature　and　ambient　temperature　was　considered,　the　influence　characteristics　of　built-in　temperatures　in　different　regions　on　the　curling　and　uplifting　of　pavement　were　analyzed　by　using　the　3D　finite　element　program.　Research　result　shows　that　slab　curling　is　affected　by　the　built-in　average　temperature　and　built-in　temperature　difference　between　slab＇s　top　and　bottom.　Annual　built-in　temperature　differences　of　cement　concrete　pavements　in　different　regions　present　the　bimodal　distribution　characteristics　with　low-wide　and　high-cuspidal　peaks　that　respectively　denote　the　distributions　of　negative　and　positive　differences.　Negative　built-in　temperature　difference　normally　forms　in　the　daytime,　and　has　a　large　variability,　which　causes　slab　corner＇s　upward　curling.　While　positive　built-in　temperature　difference　basically　forms　in　the　nighttime,　and　has　a　numerical　concentration,　which　causes　slab　corner＇s　downward　curling.　The　built-in　temperatures　of　the　pavements　in　different　regions　were　compared,　negative　built-in　temperature　difference　in　the　plateau　area　is　the　largest,　and　the　high-frequency　difference　can　reach　-17.2　in　Lhasa.　The　second　one　is　in　the　north　area　where　the　high-frequency　difference　can　reach　-13.2　in　Harbin.　Built-in　average　temperature　is　generally　negative,　and　its　distribution　is　the　single-peak　type.　The　annual　range　of　air　temperature　in　the　high　latitude　region　is　larger,　which　directly　results　in　the　larger　variation　range　of　built-in　average　temperature.　High-frequency　built-in　average　temperature　in　Harbin　is　approximately　-30.4,　and　approximately　-18.4in　Lhasa.　Negative　built-in　average　temperature　also　causes　the　downward　curling　of　slab　corner,　and　the　effect　of　built-in　average　temperature　on　the　curling　is　approximately　30%-50%　effect　of　built-in　temperature　difference　under　the　same　condition.　Different　built-in　temperatures　combined　with　local　climate　have　difference　effects　on　the　curling　and　uplifting　of　service　pavement.　When　the　negative　built-in　temperature　difference　of　-20　is　added　to　local　climate,　the　curling　of　slab　increases　by　approximately　1.5-2.0　mm.　It　is　suggested　that　pavement　structure　with　quadrangular　constraints　is　used　in　significant　curling　area　to　improve　the　engineering　performance　of　the　pavement.　©　2018,　Editorial　Department　of　Journal　of　Traffic　and　Transportation　Engineering.　All　right　reserved.
