Abstract
In the present study, finite difference method is proposed to use for the development of Mathematical model for the prediction of the pavement temperature distribution (PPTD) in flexible pavement.To simpli$ the mathematical calculation, Visual Basic language was selected to perform a progam that has a capability fc.: the Prediction of Pavement Temperature as a function of depth and time. To test its accuracy, the program was applied to predict the pavement temperature distribution on specific location in section (R12) from the Expressway No.l in Iraq. The output of this program appears to be in good agreement with the (R12) observed data. Therefore the program can be recognized for use in the prediction of the asphaltic pavement temperature distribution
