N2 - The rolling dynamic deflectometer (RDD) capable of measuring continuous deflection profiles along pavements has been used in (a) delineating problematic areas to be repaired, (b) identifying potential locations for reflective cracking, and (c) developing inputs for selecting a rehabilitation scheme. Unlike discrete testing methods, the RDD travels along a pavement and its continuous deflection profile provides 100% coverage along the pavement. However, the use of the RDD in a stationary mode, called the stationary dynamic deflectometer (SDD), is used for super-accelerated pavement testing (SAP). SAP testing is defined as the application of one million load repetitions to a full-scale pavement system in one day and evaluates the fatigue performance of in-situ pavements. The SDD applications include (a) evaluating rut resistance in a flexible pavement and fatigue-crack resistance in a rigid pavement and (b) estimating the remaining life of in-service pavements under heavy traffic loads. This paper introduces benefits of the RDD as a multipurpose pavement testing device and presents three case studies using the RDD and SDD.
