FIELD: adhesion investigation instruments. SUBSTANCE: this relates to investigation of airfield and road pavements by mechanical means. Device is of simplified design and higher measuring accuracy. Device has carriage with body, setting wheels mounted on axle-shafts, and mechanical measuring system with measuring wheel, reducer, measuring wheel loading unit, measuring converter of braking force, and calculating unit. Device is also provided with unit for determining angle between surface of pavement and reducer. Axle-shafts of carriage are made oscillating and are pivotally connected with setting wheels. Measuring system is located in body of carriage and is independent from carriage suspension. It is connected with carriage body through pivoted joint. EFFECT: higher efficiency. 2 dwg
