In this research two mathematical models namely Sigmoidal and Al-Qadi and Co Workers Models were usedto assess the predictability of complex modulus of Crumb rubber modified and virgin bitumen. Goodness of fit statisticssuch as R2and standard error ratio (Se/Sy) were used to assess the reliability of the Model. The results showed that bothsigmoidal and al Qadi and Co-workers model can be used to predict the complex modulus of bitumen. Sigmoidal modelparameters can be used to assess the ageing of bitumen in case of virgin bitumen but the model suffers from limitationfor Crumb rubber Modified bitumen (CRMB) as no specific observations could be made.
