• Abstract:
  The objective of this study was to develop an approach for incorporating techniques to interpret and evaluate deflection ; data for network-level pavement management system (PMS) applications. The first part of this research focused on ; identifying and evaluating existing techniques, seeking out those that were simple, reliable, and easy to incorporate into ; current PMS practices, as well as those that produced consistent results. The second part of the research detailed the ; development of guidelines for the application of recommended techniques and procedures for determining optimum ; falling weight deflectometer (FWD) test spacing and data collection frequency. While there are many viable techniques ; available for evaluating the structural capacity of pavements that use FWD for project-level analysis, many of these ; techniques are time consuming and require an experienced analyst. As a result, using pavement deflection testing for ; network-level analysis has been limited to date. This guide provides information for the assessment of pavement structural ; performance for PMS applications. It reflects the general findings presented in the accompanying final report, Simplified ; Techniques for Evaluation and Interpretation of Pavement Deflections for Network-Level Analysis (FHWA-HRT-12-023).
