 Falling weight Deflectometer

Falling weight Deflectometer

The falling weight Deflectometer is a non-destructive testing device used to measure pavement deflections. Flexible pavements have long been assessed by their structural capacity and by the surface conditions. The practice of determining the structural capacity of in-service pavements by the surface deflection response to a known load is widely recognized as the most effective method. Pavement surface deflections are currently measured by tools such as Falling weight Deflectometer (FWD), and Rolling Dynamic Deflectometer (RDD). Rolling Wheel Deflectometer ( RWD ) ability to measure deflections at high speeds without disruption to the traffic makes it an ideal tool to develop a structural capacity screening tool at the network level.
The Rolling Wheel Deflectometer (RWD) is capable of measuring pavement deflection at high speeds without traffic interruption or compromising safety along tested road segments. To optimize the use of RWD at the network level, an assessment tool is needed to incorporate RWD data into Pavement Management System (PMS) and to identify pavements in need of maintenance or rehabilitation. 
Flexible pavements have long been assessed by their structural capacity and by the surface conditions. The practice of determining the structural capacity of in-service pavements by the surface deflection response to a known load is widely recognized as the most effective method. The information of deflection testing at network level would be a great step forward for Pavement Management System (PMS) in identifying structurally-deficient pavements and project prioritization. Pavement surface deflections are currently measured by tools such as Falling weight Deflectometer (FWD), and Rolling Dynamic Deflectometer (RDD).
A deflection matrix developed upon pavement condition and the thickness for the RWD measurements would be an effective tool for pavement management. Such a matrix developed would identify the pavement structural conditions and feasible treatment options.
Pavement management system is a systematic process that provides, analyses and summarizes pavement information for use in selecting and implementing cost effective pavement construction, rehabilitation, and maintenance programs.
