The load data of Chinese users’ road and test field road is collected and analyzed in this paper. Through calculating the damage of each frequency band of load data,the corresponding test field feature matrix and user road target matrix are established,the equivalent load spectrum and damage model are compared,and a kind of damage model based on load frequency is set up. The model of damage correlation between user road and test field is obtained,the cycle number of different road is matched,and the optimal test standard is obtained. This paper provides a reference and technical basis for establishing a test field specification which conforms the user’s road characteristics accurately.
