Operations/Analysis Feedback Reports

 

In 1996, the Long-Term Pavement Performance (LTPP) program instituted a data analysis and operations feedback system to enable users of the LTPP database to report situations encountered during Federal Highway Administration (FHWA)-sponsored analysis of the data that suggest or demonstrate the need for corrective actions or further investigation. Use of this reporting mechanism by others was also encouraged. Applicable situations encountered include, but are not limited to:

  • The absence of critical data for specific test sections.
  • Data that appear to be incorrect, contradictory, or otherwise suspect.
  • Data that are not currently collected but that are needed to fill voids identified during analysis.
  • Recommendations arising from the analysis as to how data collection procedures might be improved.

 

A spreadsheet summary of these feedback reports by the categories below is provided here (.zip, 496 KB). Each summary provides a synopsis of the problem, the status, and the resolution. Reports are considered resolved when it has been determined whether or not a problem exists and action has been taken.

  • Distress
  • Drainage
  • Falling Weight Deflectometer (FWD)
  • Friction
  • General Pavement Studies (GPS)
  • Information Management System (IMS)
  • Materials
  • Profile
  • Seasonal Monitoring Program (SMP)
  • Specific Pavement Studies (SPS)
  • Traffic
