Decay test device and system thereof

The utility model provides a decay test device and system thereof, decay test device include the box body, go up load plate and fatigue testing machine, fatigue testing machine's last loading fixture with go up load plate fixed connection, fatigue testing machine's lower loading fixture with the bottom fixed connection of box body, the testpieces of being tested is placed in the box body, upward the load plate roof pressure is on the top surface of testpieces, and the bottom plate of box body and last load plate grasp the testpieces. The device can simulate out temperature, acid rain, villaumite and high speed train load combined action's operating mode to the more real ballastless track cement -based materials that reachs is in the dynamic behavior of actual motion in -process decay law, thereby for ballastless track fatigue life's prediction provides effective, reliable tentation data with the maintenance, with ride comfort, travelling comfort and the security that improves the high -speed railway operation
