Abstract:reviewed that the research progresses of the measurement methods of road surface and road surface profile in recent years. A new high precision road surface profile measurement system is presented and its measurement principle and testing method are introduced. Based on the road surface profile measurement system, the measurement methods of road surface true profiles are discussed. These are many contrastive tests are completed with Level and Ruler in mountains, plains, cities and the areas of GPS signals are blocked. The contrastive tests got better results. In the end, the measurement methods of the road surface profiles are summarized, the using fields and merits and drawbacks of the road surface profile measurement system are evaluated.
