METHOD TO ASSESS CONDITION OF ELEMENTS OF SOFT ROAD STRUCTURES BY SPECTRAL ANALYSIS OF WAVE FIELDS AT OPERATION STAGE Russian patent published in 2013 - IPC G01M7/00 

Abstract RU 2498254 C1

FIELD: construction.

SUBSTANCE: when the method is realised, impact force is applied on the surface of the road structure, road structure response is measured by sensors - piezoceramic vibroaccelerometers installed on the track in reference points at different distances from the centre of the contact area on the surface in parallel to the axis of the motor road. Fourier transform is applied to amplitude-time characteristic of surface points acceleration registered under impact force by sensors-accelerometers, as a result of which the amplitude-frequency acceleration characteristic is produced, and then the amplitude-frequency characteristic of movements is produced. Further the amplitude-time characteristic is produced from movements of road structure surface points by each sensor, afterwards a dynamic flexural bowl is built. Assessment of the condition of structural elements of the soft road structure is carried out by means of analysis of arrangement of frequency resonances at the amplitude-frequency characteristic of acceleration of the surface points, geometric forms of resonances, and the geometric form of the experimental dynamic flexural bowl registered on the road surface.

EFFECT: possibility to assess condition of actual values of elasticity modules of each structural layer of a road surface at the operation stage.
