The LTPP program relies on data collected by weigh-in-motion systems that measure the traffic stream The LTPP program receives and analyzes data from weigh-in-motion systems that measure traffic streams. For example, weigh-in-motion measurements collected at one location in Arizona found that traffic loads were much lower than would be typically expected based on their standard design tables. By adjusting the pavement design to reflect these lower traffic loads, the Arizona Department of Transportation was able to save more than $2 million and was then able to put those savings to work on other high-priority highway projects.
Long-Term Pavement Performance (LTPP) data are the foundation for new pavement designs for years to come. As such, data collected at LTPP test sites n...
