Graduate student presents at conference
September 5, 2018
Zafrul H. Khan, a doctoral student in the department of civil, construction and environmental engineering, and a graduate research assistant under the tutelage of Dr. Rafiqul Tarefder, presented findings of his research in the ASNT NDE/NDT for Highway and Bridges: Structural Materials Technology (SMT 2018) and the International Symposium on Non-Destructive Testing in Civil Engineering (NDT-CE 2018) on Aug. 27-29 at the Hyatt Regency and Rutgers University, New Brunswick, N.J.
His research focused upon the importance of quantifying the Asphalt Concrete (AC) damage to ensure that the flexible pavement survives its design life. However, collecting field cores and performing laboratory tests at regular interval can be costly and time consuming. Non-destructive testing method, such as Falling Weight Deflectometer (FWD), can be employed in this regard. Continuous FWD test was conducted on the I-40 instrumentation section since 2012, and AC layer degradation was evaluated.
