MACHINE DETERMINING RUTTING OF ASPHALT-CONCRETE PAVEMENTS BY ROLLING OF LOADED WHEEL (VERSIONS) Russian patent published in 2015 - IPC G01N3/56 

FIELD: testing equipment.

SUBSTANCE: invention relates to test equipment, in particular to vehicles for testing for resistance against rutting of pavements, and can be used by the appropriate industries. The vehicle contains testing thermal chamber with installed pole for sample, on which mould with tested sample is installed, testing wheel performing reciprocating movement, wheel drive, wheel loading system, control system. The wheel drive and loading system are pendulum-lever gear in which additional movable link is installed ensuring straight horizontal movement of the wheel, or wheel drive and loading system are pendulum-lever gear comprising equal-arm lever connected with the pendulum via the additional movable link ensuring straight movement of the wheel - clevis, and force actuator - pneumatic cylinder, and table is equipped with force measuring transmitter.

EFFECT: reduced covered space, simplified sample installation on the work table, exclusion of force overturning the wheel during work.
