Design of full-scale highway accelerated loading testing

The full-scale highway accelerated loading testing facility is an international fashionable and popular equipment of evaluting a commendatory reasonable pavement structure's performance, so a highway accelerated loading testing facility is developed, which has self-owned intellectual property. The mechanical structure and the control system of the highway accelerated loading testing based on CAN bus is studied, whose software and the hardware are also introduced in details in this paper, finally, the pressure acting on the road surface of the automobile tire is tested using the facility. The system can measure the related parameters in real time, the data collected is accurate and stable. the experiment shows that the system has the advantage of simple operation, high measuring accuracy and reliable running.
