A new layer moduli backcalculation procedure using transient measurements from both a falling weight deflectometer (FWD) test and a surface wave test is presented in this paper. This algorithm employs numerical solutions of a multi-layered half-space based on Hankel transforms as a forward model and Artificial Neural Networks (ANNs) for the inversion process. Two ANNs are used in series; a dept…
This paper presents a methodology based on deflection basin parameters and artificial neural networks (ANNs) for processing dynamic falling weight deflectometer (FWD) measurements to estimate layer moduli and condition. Two-dimensional, dynamic, finite element analysis using the ABAQUS program was employed to develop the deflection information for this study. Unlike the majority of the existing…
Asphalt Pavements contains the proceedings of the International Conference on Asphalt Pavements (Raleigh, North Carolina, USA, 1-5 June 2014), and discusses recent advances in theory and practice in asphalt materials and pavements. The contributions cover a wide range of topics: - Environmental protection and socio-economic impacts - Additives and modifiers for asphalt concrete - Maint…
