INSTALLATION FOR STATIC TESTING OF FLEXIBLE AERODROME PAVEMENT Russian patent published in 2024 - IPC E01C23/07 

FIELD: construction.

SUBSTANCE: invention relates to construction and operation of flexible aerodrome pavements and can be used in installations for static tests of flexible aerodrome pavement, including for determination of bearing capacity of flexible aerodrome pavements by direct measurements. Device comprises a spatial frame structure, a loading device and a loading wheel, the axis of which is connected to the frame structure with possibility of rotation. Frame structure is collapsible. Loading wheel is a pneumatic wheel with pressure of 12.5±0.5 kg/cm², which is installed along the central longitudinal axis of the frame structure. Loading device used is two synchronously operating jacks installed on the frame structure, on both sides of the wheel. Device contains two oil stations, one of which is connected through the splitter to jacks, and the other one – to the pneumatic wheel brake system.

EFFECT: simplification of static tests and higher accuracy of measurements.
