Network-Level Pavement Structural Evaluation

Abstract

This paper addresses the use of traffic-speed deflection devices for the structural evaluation of pavements at the network level as part of an effort funded by the Federal Highway Administration. Highlights from three major efforts—gathering of information to identify viable devices, field trials at or near the MnROAD facility to evaluate viable devices, and data analyses to identify and select the best deflection indices—are presented. In addition, suggestions for the implementation of the results within network-level pavement management system applications are provided and technology improvements recommended.
