Summary:Imagine measuring the load-carrying capacity of paved highways and detecting possible pavement weaknesses, while traveling with the traffic flow. No lane closures to collect data. No additional congestion. No traffic back-ups. No work zone safety issues. How? The answer is one of today's most significant innovations in pavement management systems the rolling wheel deflectometer (RWD). 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.
