Ground-coupled radar database on samples of hot-mix asphalt layers

This database was collected using several ground-penetrating radar (GPR) systems over hot-mix multi-layer samples, designed under controlled conditions. The experimentation campaign was conducted during the French research project ACIMP (ANR-18-CE22-0020), funded by the French National Research Agency (ANR). One of the project’s objective was the detection of debonded asphalt layers. The database has been extended by hot-mix asphalt samples featuring varying tack coat dosages.
