The roughness of the road surface is one of the most important indicators of the pavement quality assessment. Based on the pavement quality assessment in the analysis of road roughness,this article designs the road roughness acquisition system based on the acceleration sensor. For the hardware part of the system,the signal collecting module is developed with C8051F005 micro-controller that can measure vehicle vertical acceleration analog signal which is from negative one point two volts to one point two vol...

2.593,and the IRI of Qingfen road was 1.954,and both of them were A level road.At the same time,we usedhigh accurate laser surface flatness cytometry to do a comparative test.The experimental results showed that thescheme proposed had small errors and was
