A fuzzy logic based risk analysis model has been developed to identify and evaluate the moisture damage potential in flexible road pavements. Long term field investigations in a New Zealand road network coupled with a review of the available literature helped in identifying the possible factors that may induce moisture damage in road pavements. An inference rule (If-Then) based risk analysis model has been developed. Expert knowledge and judgment were canvassed for setting up the membership functions for the inputs and the inference rules of the model. The model has been utilized in identifying and assessing the moisture damage risk of a number of road sections in the network. Further research will identify the correlation between the moisture damage risk and pavement distresses (rutting, roughness, flushing). This will be helpful in validating the proposed risk analysis model.
