Measurement and Application of Road Profile

摘要

It's reviewed that the research progresses of the measurement methods of road profile and road surface spectrum in recent years. A new measurement method of road profile is presented and a high precision road surface profile measurement system (RSPMS) is developed. The measurement principle and testing method of RSPMS are introduced. Based on the measurement device, these are many contrastive tests are completed with Level and Ruler to get the measurement precision of the RSPMS. The contrastive tests consisted mostly of small wavelength signals and large wavelength signals and got better results. Another, the applications of the road profile data are discussed. In the end, the merits and drawbacks of the measurement method are evaluated and the using fields of the road profile data are summarized.
