    Abstract
  • With the development of pavement testing equipment, especially with the usage of laser equipment, it is possible to analyze pavement power spectral density (PPSD) exactly.Based on the analysis of testing data of long term pavement performance, it is concluded that PPSD is a good tool to analyze the pavement performance and auto-pavement dynamic loading. The limitation of ISO standard was also discussed, and a better pavement classification method with PPSD area was promoted.
