[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

Tentative Scope

Pavement condition data is a critical component of all pavement management systems. The accuracy and validity of pavement condition data is crucial to many activities conducted by highway and local agencies. Pavement condition data is used, for example, to assess existing and future pavement condition, establish budget needs and evaluate budget impacts, support asset management, and select projects for pavement maintenance and rehabilitation. The new federal transportation bill (National Performance Management Measures; Assessing Pavement Condition for the National Highway Performance Program and Bridge Condition for the National Highway Performance Program) is performance-based and agencies will be required to report pavement condition of highways on the National Highway System (NHS). Pavement condition reporting will include the International Roughness Index (IRI), rut depth, and percent cracking for flexible pavements, IRI, percent cracking, and faulting for jointed concrete pavements, and IRI and percent cracking for continuously reinforced concrete pavements.

The new bill requires agencies to report pavement condition based on 0.1 mile intervals. This interval of data reporting can only be effectively achieved using automated pavement condition data collection systems. Manual ratings are very impractical and labor intensive for collecting pavement condition at 0.1 mile intervals. Several agencies have implemented automated pavement data collection for several years now. It is important to learn from their experience and the improvements in the process over the years. This will be very beneficial to states that are just moving into automated pavement data collection or states with limited experience.

The objective of this synthesis is to document agency practices, challenges, and success in conducting automated pavement condition data collection surveys. The study is intended to showcase successful practices, integration of automated data collection into pavement management systems, and efforts needed for reporting pavement condition according to the new federal transportation bill.

Information to be collected, but not limited to, includes:

• Pavement distress types collected using 2-D and 3-D technology.
• Post processing requirements (data and images).
• Service provider and highway agency quality control, acceptance, and independent assurance procedures.
• Acceptance and verification of data accuracy and repeatability (2-D and 3-D technology).
• Quality management plans.
• Data storage and archiving requirements.

Information will be collected through literature review, a survey of state departments of transportation and Canadian provincial transportation agencies DOT, and selected follow up interviews for case examples.
