MANUAL OF OPERATION AND USE OF DYNAFLECT FOR PAVEMENT EVALUATION

This manual was developed to provide assistance in the interpretation of dynamic deflection measurements obtained with the Dynaflect trailer and guidelines for the design of pavement overlays utilizing these data. Discussions relating to the significance of the individual deflection readings and mathematical parameters derived from these deflections are also included. Figures are presented, along with example problems, which demonstrate a graphical procedure for the design of overlay thicknesses for various types of pavement. The manual describes how Dynaflect data are collected and processed in Ohio with sample computer output and plots shown. Operating instructions and field-oriented trouble-shooting hints for the Dynaflect are also included. (FHWA)
