The process of airport pavement destroyed by loads such as wheel crushed down during pave-ment operation can be regarded as a process of unfavorable disturbance,and the ability of the pavement system characterized by adopting the pavement resilience index unfavorable for defending against adverse disturbances and recovering from disturbances is a hot research issue.In this paper,first,an index node for pavement resilience evaluation is established by introducing an economic index in combination with pavement condition index,pavement structural condition index,pavement flatness index and pavement friction coefficient.And then,the topological network is constructed based on the node relationships ac-cording to the topology theory,and the strength of nodes is calculated based on the theory of toughness triangle.Finally,the resilience in the airport pavement system is determined by calculating the overall strength of the topological network.The Tianshui Airport's pavement resilience index is measured by this measure,and the results show that the evaluation method is"good",and can provide an important refer-ence for the evaluation of the safe operation of the airport pavement system.
