Road surface accelerating loading experimental device

Abstract

The invention provides a pavement accelerating and loading experimental device, pertaining to experimental facility field. The invented device comprises a main framework, and a rail assembly connected to a rolling assembly is disposed on the main framework. The invented device is characterized in that the rolling assembly comprises both a drive wheel connected to the power device and more than one driven wheels disconnected from the power device, thereby pavement rolling status when vehicles run thereon practically can be reproduced better to enhance accuracy of experimental conclusion and efficiency of the experiment. The invented device is also characterized in that the outer circular surfaces of the loading steel wheel and the return-stroke steel wheel are provided with outwards inclined treads, auto direction guide is implemented, and cylindrical wheel guide is not needed, so that structure is simplified and noise is decreased.

Description

(1) Technical field [0001] The invention relates to a test device, in particular to a road surface accelerated loading test device. (2) Background technology [0002] Accelerated pavement loading test equipment is a special equipment for testing and testing pavement materials and structures. The rolling device of the existing pavement accelerated loading test equipment mainly adopts single-axis (single-wheel or double-wheel) active or driven rolling type, and the loading part mainly adopts self-weight loading or cylindrical wheel reverse loading, and is equipped with lateral cylindrical Wheel-guided loading type. There is a large difference between the rolling of the road surface by the single-axis (single-wheel or double-wheel) active or driven rolling type and the rolling of the road surface when the vehicle is actually running, and the test detection is inaccurate; and the road surface in a cycle The rolling is only once, and the work efficiency is low; the mass of the ...
