This report documents the results of a study that evaluated current technologies implemented
in continuous deflection measuring devices. The research team assessed the demand and …

Continuous deflection devices (CDDs) can safely measure pavement deflection (or other
related properties) while traveling at highway speed, which reduces traffic disruption. CDD …

Continuous deflection-measuring devices, or continuous deflectometers, are increasingly
being used to support project-level and network-level pavement management decisions. …

This article uses the limits of agreement (LOA) method to compare the falling weight deflectometer
(FWD) and the traffic speed deflectometer (TSD), two pavement structural evaluation …

One of the headline objectives of the UK Highways Agency (HA) is to reduce congestion and
improve road safety while undertaking necessary highway maintenance. To this end, HA …

Improved strategies for design and condition assessment are required for flexible pavements,
which carry the heaviest volumes of traffic, to decrease the need for maintenance and …

This paper explains some of the historical developments that lead to the discovery of the
unexpected pavement deterioration modes that are an inherent part of the flexible long life …

Continuous deflection measuring devices, also called continuous deflectometers, are
increasingly being used to support project-level and network-level pavement management …

One of the main difficulties that arise during the analysis of continuous deflection measurements
is the reduction of measurement variability (noise) without smoothing out important …
