Abstract
An accelerated loading road-testing system includes a plurality of loading mechanisms that are sequentially arranged along a first direction. The loading mechanism includes a supporting frame, a sliding assembly, and a loading assembly. The supporting frame includes a horizontal supporting beam disposed along a second direction. The sliding assembly is slidable on the horizontal supporting beam along the second direction. The loading assembly includes a telescopic cylinder and a loading head. A first end of the telescopic cylinder is hinged to the sliding assembly, the 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.
