The study results indicate that FWD testing with advanced analysis can be successfully used to evaluate in situ pavement condition from structural point of view.9781840463996 1840463996 Fighting Fantasy Posterĩ788466319522 8466319522 La Vida Nueva, Orhan PamukĠ16728502627 0016728502627 Migration CD (2007), Antonio Sanchez, Joe Ferla, Bernie Kirsh. The deterioration trend of AC modulus was found consistent with fatigue cracking measured at pavement surface based on field distress survey results. The slight modulus degradation was observed in granular base layer and subgrade. On the other hand, the nonlinearity parameters obtained from backcalculation can be used to characterize modulus distribution at different depths in granular base layer and subgrade. The relatively greater variation of modulus degradation was observed for dynamic modulus in the high frequency range. As damage developed in AC layer over years, the master curve of AC dynamic moduli showed the similar sigmoidal shapes but the modulus decreases as compared to the undamaged AC. Three pavement sections with FWD testing conducted at different time periods were used in the analysis. An integrated Artificial Neural Network – Genetic Algorithm (ANN-GA) program was developed to backcalculate layer moduli using pavement surface deflection measured under falling weight deflectometer (FWD) test.
This study aims to assess asphalt pavement condition in terms of backcalculated moduli of asphalt concrete (AC) and unbound material layers.
