LTPP Analysis Task Order: Simplified Techniques for Evaluation and Interpretation of Pavement Deflections for Network-Level Analysis

The primary objective of this study is to identify or develop, verify, and recommend simplified deflection-based analytical techniques suitable for rapid, automated screening of pavement structural capacity for inclusion in network-level PMS. These techniques will be derived from information gathered from Long Term Pavement Performance (LTPP) and from states currently using structural information in their PMS. The success of the study will hinge on identifying solutions that can be readily implemented in State and local municipality systems. The second objective of the study is to develop and recommend data collection procedures that will maximize testing productivity and minimize risk while still providing adequate information for use in the PMS. Spacing and frequency of data collection are the two primary parameters of interest. The recommendations should consider both the incremental cost of collecting the data and benefits of better prediction and decision making. The third objective of this study is to ensure that the results are applicable to agencies that do not use deflection testing in their PMS but use nondestructive deflection testing as part of their project-level analysis and design activities.
