The invention belongs to the field of road engineering and discloses a rutting plate forming device with a shear resistance testing function. The device comprises a rolling and loading component, a forming and heating component, a supporting and demolding component, a movable driving component, a driving supporting motor, a shearing component and a control component. According to the device, single-layer and double-layer rutting plate forming and shear resistance tests are realized, the internal temperature and the interlayer stress state of the asphalt pavement under actual working conditionsare simulated, the problems that an asphalt mixture rutting plate test piece is complex in forming and inconvenient to demold, stress and temperature of the test piece are inconsistent with reality and the like are solved, the forming efficiency of the test piece is improved, the test error of a traditional shear test is reduced, and the development prospect is wide.
