Evolutionary Algorithms and their Applications in Civil Engineering - 2

This document discusses the application of linear elastic layer theory and backcalculation to evaluate flexible pavements. It describes how a falling weight deflectometer can be used to measure the deformation of a pavement under a load and at different radial distances. Linear elastic layer theory can then be used to model the surface deflections based on pavement properties like layer moduli and thicknesses. Backcalculation is used to determine the modulus values of layers by minimizing the difference between measured and modeled deflections. Genetic algorithms and ant colony optimization have also been applied to backcalculate pavement moduli.
