The deflections measured on flexible pavements by the Dynaflect system have been correlated to those obtained by the Benkleman Beam by a number of research groups In highway departments and universities. In addition to being able to make deflection measurements, the shape of the deflection basin can be readily determined.

Accurate deflection measurements have been made on rigid pavements as thick as 24". The extent of the deflection basin in rigid structures can easily be defined with the Dynaflect system.

The Dynaflect system, is designed to operate behind any vehicle that has a trailer hitch and a 12 volt battery system. The Dynaflect unit Is a self-contained trailer with a control box so that the operation can be performed by one man. Deflection measurements can easily be made on any surface that Is accessible to the tow vehicle and the trailer. Thus, the Dynaflect system Is more of a universal tool than any of the previously used systems. The lightweight design and the mode of operation make the Dynaflect system a practical tool for use In all phases of roadway or airport runway construction, as well as a maintenance tool to evaluate existing pavements to determine the overlay requirements or other preventative maintenance needs.
