Using Falling Weight Deflectometer Data with Mechanistic-Empirical Design and Analysis
Project Information
Project ID:
FHWA-PROJ-21-0001
Project Abstract:
In spite of the rapid advances in computing technology and power during last decade, the procedures for routine backcalculation and interpretation of falling weight deflectometer (FWD) data has seen little change. A significant percentage of most State Highway Agency pavement activities relate to rehabilitation of existing pavements, and the effective use of nondestructive field testing, such as FWD testing, for the evaluation of in-service pavements will be key to an efficient approach.
One of the objectives of this project is to review the current state of the practice and art in routine backcalculation of FWD data and develop recommendations for advancing FWD data analysis and interpretation, particularly in relevance to the rehabilitation procedures in the Mechanistic-Empirical Pavement Design Guide (MEPDG) developed under the NCHRP 1-37A project. This project will also develop best practices guideline for analyzing and interpreting FWD data for project level analyses with particular emphasis on the effective and efficient use of FWD data with the MEPDG.
