A new system can be used for assessing the condition of hot-mix asphalt (HMA) pavements to detect debonding between HMA layers. The study was partly funded by a SHRP 2 project through the National Center for Asphalt Technology. The objective was to develop a reliable technique for determining the internal condition of HMA pavements that included debonding conditions between each layer. A prototype of an impact echo and spectral analysis of surface waves scanner (originally developed for assessment of bridge deck condition) with up to three pairs of transducer wheels was used in the project. Background on the development of the scanner and a case study performed on HMA pavements of known conditions at the National Center for Asphalt Technology’s pavement test track are presented. The research investigation was performed as a blind study, and the actual pavement conditions were revealed to the research team after the initial data analysis and reporting of detected delamination conditions were completed.
