摘　　要：根据改扩建道路的路面结构性、功能性要求以及材料疲劳性能,提出了拓宽道路工后差异沉降分级标准及控制指标,并与基于路面结构使用性能的PSI法路面使用状况分级相比较,发现两者之间具有良好的相关性。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.
