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).
