This study introduces a backcalculation algorithm to estimate the material properties of the full-depth asphalt pavements. The proposed algorithm, namely CS-ANN, uses an Artificial Neural Network (ANN) based forward response engine, which is developed from the solutions of nonlinear finite element analysis to calculate the deflections mathematically. In the backward phase of the method, Cuckoo Search (CS), is utilized to search for the layer moduli values. The performance of the proposed method is investigated by analyzing the synthetically calculated deflections by a finite element based software and deflection data obtained from the field. In addition, to evaluate the searching capability of CS, optimization algorithms widely used in pavement backcalculation; Genetic Algorithms (GA), Particle Swarm Optimization (PSO), and Gravitational Search Algorithm (GSA), are employed for comparison purposes. Obtained results indicate that the proposed backcalculation approach is able to determine stiffness-related layer properties in an accurate and rapid manner. In addition, CS presents a promising performance in reaching the optimum solutions that are better than GA, PSO, and GSA.

Investigation of variations in performance properties of asphalt concrete using image-based finite element model
Karakaya, Yalçın; Güler, Murat; Department of Civil Engineering (2022-7-20)
The objective of this study is to evaluate variations in performance properties of asphalt concrete using a two-dimensional image-based finite element model. Two different asphalt mixtures are used in both laboratory tests and in FEM analyses representing different conditions. A flatbed scanner is then used to capture cross-sectional images of the samples and various image processing techniques are applied to prepare the images for FEM. A unique image vectorization method has been developed to transform cro...
Numerical modelling of continuous transverse grates for hydraulic efficiency /
Sezenöz, Berk; Tiğrek, Şahnaz; Department of Civil Engineering (2014)
In this study, numerical analyses of newly proposed grated inlet system for small roads are carried out. The model is based on a setup constructed in Hydromechanics Laboratory of METU. The physical model which is a rectangular channel of 0.9m width acts as a small road and continuous transverse grate system is installed as an inlet structure. The physical conditions were modeled by using Flow 3D software. The rates of the intercepted flows are measured and compared with the results of experimental data coll...
Soft computing methodology to determine pavement thickness from falling weight deflectometer testing
Pekcan, Onur; Ghaboussi, J. (2010-12-01)
This paper describes an advanced pavement analysis application based on a soft computing methodology, SOFTSYS, recently developed at the University of Illinois for identifying pavement geometry and layer properties through various nondestructive testing methods. Specifically, it is capable of backcalculating pavement layer properties as well as determining thickness of full depth asphalt pavements using results of the Falling Weight Deflectometer (FWD) test. SOFTSYS uses a combination of Genetic Algorithms ...
A gas-kinetic BGK scheme for parallel solution of 3-D viscous flows on unstructured hybrid grids
Ilgaz, Murat; Tuncer, İsmail Hakkı (2007-01-01)
In this study, a gas-kinetic BGK scheme for the solution of 3-D viscous flows on unstructured hybrid grids is presented. The second order accurate finite volume formulations are given. In order to accurately resolve the boundary layers in wall bounded viscous flows, hexahedral grid cells are employed in the boundary layer regions normal to solid surfaces while the rest of the domain is discretized by tetrahedral cells. The computation time, which is an important deficiency of gas-kinetic BGK schemes, is imp...
Evaluation of topological forms for weight-effective optimum design of single-span steel truss bridges
Hasançebi, Oğuzhan (2011-08-01)
This paper reports a comparative study on design weight efficiency of single span steel truss bridge topologies subjected to gravity loads. The bridges configured according to nine distinct topological forms (namely, Pratt, Parker, Baltimore, Petit, K-Truss, Warren, Subdivided Warren, Quadrangular Warren and Whipple) are designed for minimum weight under various span length requirements of single span truss bridges, and the results obtained with these topological forms are compared. The optimization process...
