This paper addresses the use of traffic speed deflection devices for the structural evaluation of pavements at the network-level. At the heart of the decision making process is the pavement management system (PMS), which provides condition indices or scores for each pavement segment in the network. Current PMS are driven by distress and ride quality as key pavement condition indicators. Both merit emphasis within the PMS process, but another important indicator to making rational pavement investment decisions is the structural adequacy, which is most often determined based on deflection testing.
