1. An accelerated loading road-testing device, comprising a plurality of loading mechanisms, wherein the plurality of loading mechanisms are sequentially arranged along a first direction, wherein each of the plurality of loading mechanisms comprises:
a supporting frame, comprising a horizontal supporting beam, the horizontal supporting beam is disposed along a second direction, and has a sliding state in which the horizontal supporting beam slides along a third direction, and a static state in which the horizontal supporting beam is static;
a sliding assembly, disposed on the horizontal supporting beam, and slidable on the horizontal supporting beam along the second direction;
a loading assembly, comprising a telescopic cylinder and a loading head, wherein a first end of the telescopic cylinder is hinged to the sliding assembly, a second end of the telescopic cylinder is securely connected to the loading head, the telescopic cylinder is configured to drive the loading head to move along the third direction, the loading head is configured to interact with a road surface to be tested in order to adjust an angle between the telescopic cylinder and the sliding assembly and is configured to always apply a load to a road surface to be tested in a direction perpendicular to the road surface to be tested, and the first direction, the second direction and the third direction are perpendicular to one another.
