FIELD: testing technology.
SUBSTANCE: according to the first embodiment, the device of cyclic loading comprises a box for a sample, a control unit, a force sensor. The plate for sample loading is connected to the force sensor, the gear drive. The force is transmitted by the pneumo-muscle through the gear and the lever, and the position of the lever is controlled by the lever position sensor. The compressor provides the operating pressure of the pressure regulator. According to the second embodiment, in addition to all the above in the first embodiment, the storage tank is added in the device, between the compressor and the pressure regulator.
EFFECT: opportunity to evaluate the wear of materials of roadway surfacing under the action of cyclic loading.
