ABSTRACT
The design of pavement systems requires several input parameters that possess specific levels of uncertainty. Quantification of such uncertainty is deemed necessary for reducing the level of risk associated with the design. This study aims at quantifying the effect of the randomness within the elastic modulus of concrete on the design and performance of rigid pavements. The randomness of the elastic modulus of concrete is quantified using the Hirsch model and represented by a normal distribution. Linear regression analysis is later conducted to investigate the relationship between the elastic modulus of concrete and the slab design thickness of a rigid pavement.
