The invention discloses a vehicle axle load spectrum and road surface response synchronous measurement system and method. A detection module comprises induction units arranged at an entrance and an exit of a detection area, and an axle load measurement unit and a response measurement unit which are arranged in the detection area; the data acquisition module is used for acquiring an axle load measurement signal, a response measurement signal and a high-low level signal of the sensing unit, and storing the signals into a dynamic array; and the data analysis module is configured to extract the measurement signal of each unit from the dynamic array and obtain the change of the vehicle axle load and the driving track of a certain vehicle type to the response of the road surface according to the data of each unit. Acquisition of the vehicle speed, the vehicle model, the axle load and the vehicle driving track is achieved, the position of the tire acting on the road surface is obtained through the vehicle driving tr
