FWD 처짐치에 의한 포장층 탄성계수 역산 및 해석기법

Back calculation and solution Technique of E-modulus by FWD′s deflection data in Pavement

In this study, a pavement evaluation method is introduced by a case study of the measurement data obtained in Incheon International Airport. Based on the results obtained by both visual inspection and automobile inspection equipments, the pavement surface condition is evaluated and used for maintenance and rehabilitation strategy for pavement. In addition, the special attention was given to the back calculation and solution technique of E-modulus by FWD's deflection data in Pavement.
