FIELD: test.
SUBSTANCE: invention is related to testing equipment. Proposed device comprises loading plate to interact with tested surface, force transfer means to transfer force to load plate, shock absorbers and falling load. Falling load is intended for impact by means of force transfer through shock-absorbing facilities with creation of force transferred to loading plate through means of force transfer. Device also comprises at least one linear electric motor for lifting of falling load at specified height above means of force transfer.
EFFECT: invention can be used for assessment of physical properties of road pavement structure.
