FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of construction and is designed to define mechanical properties of construction and road materials, including reinforced soils, under complicated stressed-deformed condition. The device comprises a frame, a body with a base, a cover and side walls, a working chamber with an elastic shell and pressure chambers arranged in it and joined with loading and metering accessories. One of side walls of the body is arranged as rigid and movable with inbuilt force sensors, besides, displacement of the wall is monitored with a step motor, and the material sample is lifted using a movable platform with a hydraulic drive.
EFFECT: expansion of instrument functionality and increased accuracy of research by measurement of contact stresses and local deformations.
