Interstate Highway Pavement Sampling Data Quality Management Plan
Primary Topic: Pavement Management
Description: The regulations implementing the MAP-21 and FAST ACT surface transportation authorization bills have required that a Pavement Data Quality Management Plan be developed and followed for the collection and processing of all data collection used for evaluating pavement performance. Because the measures rely on pavement condition data stored in the Highway Performance Monitoring System (HPMS), FHWA undertook a study in 2015 to: (1) collect an unbiased baseline condition of a statistically significant sample of the entire IHS and produce a report indicating the pavement condition on the IHS nationally and in each State where data were collected, (2) determine if HPMS is an unbiased representation of the pavement condition of the IHS, and (3) recommend improvements to HPMS data collection and reporting necessary to make HPMS unbiased or improve its precision. The results provided the outcomes needed at the time. At the present time, FHWA has contracted a follow-up study addressing the similar objectives involving collection of 7500 miles of data describing the condition of pavements on the Interstate System and certain analyses that will be conducted using that data. As a critical part of this study, this quality management plan for data collection and analysis has been completed in advance of the data collection effort.
