In order to provide a decisionmaking basis for pavement maintenance managers, a judgment standard system for preventive maintenance of cement concrete pavement is established. Based on the research results of pavement antisliding performance evaluation index and pavement condition index preventive maintenance standard, and according to the basic assumption of the interaction between evenness and dynamic load in the process of cement concrete pavement decay, the judgment standards of friction coefficient, international pavement evenness index, pavement damage index and single index of dominant disease are studied by using the derivative inflection point method and confusion matrix model. This paper analyzes the function and judging principle of each index in the perspective of judging dimension, comprehensive dimension and controlling dimension, forming the judging standard system of preventive maintenance of cement concrete pavement in military airport. The results show that the criteria for preventive maintenance of cement concrete pavement are as follows: Friction coefficient (runway friction test vehicle 95 km/h)≥0.41; Friction coefficient (runway friction test vehicle/65 km•h-1)≥0.50; Friction coefficient (pendulum friction instrument)≥0.51; International flatness index≤3.2 m/km; Pavement damage index (3%, 10%); Corner peeling rate≤35%; Surface peeling rate≤30%; Surface crack rate≤8%; And interplate slip rate≤0.5%. The cement concrete pavement of a military airport can be provided with this scientific basis in determining the best time of preventive maintenance.
