LTPP Analysis Task Order: Integrating Condition Measurement Variability in Network Pavement Management Systems

The objective of this research project are to: (1) Review the results of current research. (2) Develop a statement of variability, precision and bias for each of the condition assessments (surface distress, friction, deflection, and profile) found in the LTPP database. (3) Develop guidelines for defining measurements required to compare performance of different pavements based on the level of variability anticipated in the condition data collected. (4) Results should be of the format that can be included as a module in an existing National Highway Institute (NHI) course. And can be used by State DOT pavement management and data collection engineers to determine the value of various distress items that are collected and used in network level analysis.
