| Abstract: | According to the road structural, functional requirements, as well as material fatigue properties of a widening expressway, the standards of classification and control index of differential settlement were put forward. Compared with the criterion of the road condition classification based on PSI of pavement structure performances, the facts indicated that there is a high linear correlation between them. |
