This session focuses on recent advances in pavement structural evaluation spanning traffic-speed testing, impact deflection methods, and embedded sensing technologies. Topics include the capabilities and limitations of TSDD systems, the use of heavy-weight deflectometers on non-traditional pavement structures, and piezoelectric sensors for sublayer stiffness and strain assessment. The presentations frame these approaches as complementary rather than competing, while openly addressing data interpretation challenges and barriers to practical deployment.
