STAND FOR MAKING SAMPLES OF ROAD SURFACES Russian patent published in 2024 - IPC G01M17/02 

FIELD: materials testing.

SUBSTANCE: stand for making road pavement samples contains a mould in the form of a tray, open at the top. Above this tray there is a unit for adjustable pressure on the mixture, made in the form of a body with an arc-shaped surface facing the tray, and fixed to the frame through a hinge with the ability to swing around a horizontal axis and with the possibility of adjustable movement towards the tray. The tray is made with rolling supports on the sides and a hinge-link mechanism. Two guides, spaced apart relative to each other, arched along a trajectory with the same radius of curvature, are mounted on the frame. The grooves of the guides contain the rolling supports of the tray. The arc-shaped generatrix of the surface of the body of the adjustable pressure unit is located across the tray. And the wall of the bottom of the tray is made arc-shaped with a radius of curvature equal to the radius of curvature of the guides.

EFFECT: it is possible to produce coating samples increased in length with a compaction structure that is as close as possible to the structure of the road surface rolled by a road roller.
