Traditional pavement deterioration modeling is normally based on historical condition data alone without incorporating the fundamental relationships between the causal factors and the response. Also, typical approaches do not quantify the uncertainty

Frost related damage in pavements is a major concern for highway engineers in cold regions. The existing methods for mitigating frost damage in flexible pavements are expensive; they require greater construction control and are not fully effective. T
