This report documents the research performed on evaluation of pavement deflection equipment under Contract DTFH61-85-C-00115 for the Federal Highway Administration. The following devices were included in side-by-side field tests conducted in the Austin, Texas area during the week of August 11, 1986: the Benkelman Beam, C.E.B.T.P. Curviameter, Dynaflect, Dynatest Falling Weight Deflectometer (FWD), Kuab FWD, Phonix FWD, and the Road Rater. The report includes descriptions and comparisons of the devices through information obtained from a literature search, field tests and user survey conducted for this study. The side-by-side test program was performed over a broad range of pavement structures, including thick and thin flexible and rigid pavements, and composite pavements. The measured deflections were compared statistically. Mechanistic interpretations of the measured deflection basins were made and compared.

In this study, the research efforts were directed toward the development of pavement condition evaluation techniques and analysis procedures for flexible and rigid overlay pavement design. This investigation also included a detailed field evaluation of an experimental portland cement concrete pavement and the analysis of deflection responses of various test sites. A stepwise regression analysis was carried out to evaluate the relative significance of various design and construction variables on the pavement deflection under load. Various techniques recommended for pavement condition evaluation of pavement structures is reviewed and the Lin-Majidzadeh investigation of dimensional analysis using the pi term concept is presented.

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).
