To obtain the correlation and variation laws between the performance indexes of expressway asphalt pavement,this paper conducted multiple tracking detections on single expressways less than 3 years old and simultaneous tests on expressways more than 3 years old.The index values of pavement distress ratio,international roughness index,rutting depth index,lateral force coefficient,and tectonic depth were obtained,and the relation between each index and road age and the correlation between the indexes were analyzed.The results showed that the indexes of single road sections all had a strong correlation,and the correlation between the international roughness index and the rutting depth index and the pavement structural strength coefficient between multiple road sections was more obvious.
