Abstract
This article discusses the rolling wheel deflectometer (RWD), one of the most significant innovations in pavement management systems, because it enables highway engineers to evaluate pavement while keeping pace with traffic. The benefit of the RWD is that it helps officials prioritize and target funding and projects to those segments of the highway network that need structural improvement and rehabilitation. Findings are presented from a series of tests conducted on the RWD by the U.S. Federal Highway Administration on a network of highways in Texas.
