• Concrete bridge
• Axle-equivalent
• Fatigue-equivalent principle

An axle-equivalent system was conducted for the concrete bridge deck thin pavement design according to classification of failure types. Based on indoor experiments and theoretical analysis, the mechanical characteristics of three different axle types was studied, which were corresponding with the other two typical pavement structures, and also the parameters of each axle's equivalent formula was put forward. Including the influential factors such as climate, environment, traffic and load condition, the developed axle equivalent formula and the parameters were modified by the field test data. The achieved axle-equivalent method can be applied in the design of a new concrete bridge deck thin pavement and the assessment of an existing concrete bridge deck thin pavement.
