Based　on　field　tests,　the　early-age　temperature　of　cement　concrete　pavement　was　analysed　firstly.　Then　combining　existing　studies　and　construction　technique,　models　and　parameters　of　hydration　heat　evolution,　environment　and　heat　exchange　were　selected.　Using　heat　transfer　theory　and　the　finite　difference　method,　a　numerical　simulation　program　of　early-age　temperature　for　cement　concrete　pavements　is　developed.　The　program　can　consider　cement　concrete　material　characteristics　and　construction　technology　in　China.　Then　spot　meteorological　monitoring,　temperature　survey　tests　of　early-age　and　long-term　for　full-size　pavements　and　small　slab　experiments　in　the　lab　testified　the　program＇s　applicability　respectively.　The　parameter　sensibility　analyzed　by　the　program　shows　that　primary　factors　affecting　early-age　temperature　of　pavements　are　material　structure　parameters,　ambient　parameters,　maintaining　methods,　paving　time,　concrete　placement　temperature,　solar　absorptivity　and　thermal　conductivity　which　affect　obviously　by　early　age.　It　is　recommended　to　study　and　modify　the　concrete　hydration　heat　evolution　model　as　well　as　the　influence　of　admixture　component　on　hydration　time　parameter　and　hydration　slope　parameter.
