Abstract

The invention provides an accelerating loading experimental system for a highway pavement. The system comprises a control device, a portal frame and a scanning device, wherein the portal frame is arranged on the highway pavement; the scanning device is arranged at the top of the vehicle; a position label is arranged on the inner side at the top of the portal frame; the scanning device is used for scanning the top of the portal frame and sending the scanned first image information to the control device; the control device is used for confirming offset degree of a first driving track of the vehicle passing by the portal frame at this time relative to a preset second driving track according to a position relationship between a first position label in the first image information and a second position label in the preset second image information, adjusting the driving track of the vehicle according to the offset degree and controlling the vehicle to drive in an accelerating and loading form on the highway pavement according to the preset condition and the preset track. By virtue of the system provided by the invention, the manual intervention can be completely avoided in the accelerating loading process of the vehicle and the automatic accelerating loading can be realized, so that the accuracy of the accelerating and loading of the vehicle can be increased.

Description

technical field [0001] The invention relates to the field of highway pavement performance detection, in particular to a highway pavement accelerated loading experimental system. Background technique [0002] With the rapid development of the transportation industry, the performance of highway pavement (such as smoothness, skid resistance, etc.) is closely related to people's travel. In order to obtain a better road paving method, it is necessary to conduct vehicle acceleration loading experiments on the paved road surface, and test the performance of the road surface according to the data of the accelerated loading experiment. At present, when performing acceleration loading experiments, it is usually necessary to manually intervene in the acceleration loading driving of the vehicle, so there is a problem of low accuracy, which leads to low accuracy of the data obtained in the acceleration loading experiment. Contents of the invention [0003] The invention provides a hig...
