Check the materials and loading data.” Usually, the 3D-Move Analysis software creates many data files such as loading, materials, input and output files. The following warning was displayed while analyzing some problems in 3D-Move Analysis version 1.2: “Error in creating the output file. A few users reported an error in creating the loading and materials data files. After releasing, there have been some problems related to material properties and load input files. The last beta-version of the 3D-Move Analysis (ver. In addition, a variety of non-highway vehicles (e.g., End-Dump Truck and Forklift et.) can also be considered. 2.0) includes Pavement Performance Models, using which many important pavement distress modes can be investigated.

These verification studies have validated the applicability and versatility of the approach.The 3D-Move Analysis (ver. Many attempts that included field calibrations (e.g., Penn State University test track, Mn/Road and UNR Off-road Vehicle study) that compared a variety of independently-measured pavement responses (stresses, strains, and displacements) with those computed have been reported in the literature (Siddharthan et al.

Frequency-domain solutions are adopted in 3D-Move Analysis, which enables the direct use of the frequency sweep test data of HMA mixture in the analysis. Since rate-dependant material properties (viscoelastic) can be accommodated by the approach, it is an ideal tool to model the behavior of asphalt concrete (AC) layer and also to study pavement response as a function of vehicle speed. This is because often times the pavements are horizontally layered and pavement responses are customarily required only at a few selected locations and for such problems the finite layer approach of 3D-Move Analysis is ideally suited. The finite-layer method is much more computationally efficient than the moving load models based on the finite element method (Huhtala and Pihlajamaki 1992 Al-Qadi and Wang 2009). Since the tire imprint can be of any shape, this approach is suitable to analyze tire imprints, including those generated by wide-base tires (Siddharthan et al. This approach treats each pavement layer as a continuum and uses the Fourier transform technique therefore, it can handle complex surface loadings such as multiple loads and non-uniform tire pavement contact stress distribution. The 3D-Move Analysis model can account for important pavement response factors such as the moving traffic-induced complex 3D contact stress distributions (normal and shear) of any shape, vehicle speed, and viscoelastic material characterization for the pavement layers. The analytical model (3D-Move) adopted here to undertake the pavement response computations uses a continuum-based finite-layer approach.
