ABSTRACT

Pavement system in the Kingdom of Saudi Arabia is experiencing an early rutting problem in the flexible asphaltic pavements. This problem has attracted the attention of many researchers and highway authorities to study and introduce means of solving it by predicting, correcting, minimizing, or preventing It. This paper presents the generation of necessary input variables used in VESYS-3AM computer program in order to calibrate and verify this model and generalize it for local use. Some road sections in the Eastern Province of Saudi Arabia were selected for this study and it was found that VESYS model, after calibration using the shift factor concept, has a good correlation in rut depth prediction so it can be used locally.
