This database was collected over narrow artificial disbonded areas during an accelerated pavement testing at univ. Gustave Eiffel's carousel. GPR data have been collected over tenartificial defects (tack-free, geotextile and sand-based), which were embedded between the top and the base layers. The data collection was organized in a two-stage experiments and covers the full life-cycle of the pavement structure. During the first stage that took place in 2012-13, data were collected at different stages from 0k to 300k loading cycles. The second measurement campaign was performed in 2019-2020 and lasted up to 800k loading cycles. This database completes a first one dedicated to three largest defects, and presented in " Radar database over large debonded areas into pavement structures
