Bridge and pavement wheel type load fatigue test system

The utility model discloses a bridge and pavement wheel type load fatigue test system. A reaction frame system provides a space required by test development; the actuator is mounted on the reaction frame system and positioned above the test piece, and provides a load required by the test; the force sensor is used for collecting the load of the actuator and providing feedback for the control system; the control system is used for adjusting the load of the actuator and controlling the loading value of the actuator; the spring clamping arm is mounted below the actuator, is hinged to the wheel load simulation device, and is used for pushing a roller of the wheel load simulation device to roll horizontally and providing a wheel pressure load for the test piece; the wheel load simulation device is provided with at least one group of rollers acting on the test piece; the loading table is used for fixedly placing a test piece. According to the utility model, single-wheel and multi-wheel bidirectional loading is reali
