Nondestructive testing provides ideal means to test pavement structure in a rapid and
convenient manner. In last few years, significant development has taken place in this field …

The backcalculation procedures are separated into five categories;(a) static linear elastic,(b)
static nonlinear elastic,(c) dynamic linear using frequency domain fitting,(d) dynamic linear …

Efforts have been made in this paper to backcalculate the in situ elastic moduli of asphalt
pavement from synthetically derived falling weight deflectometer (FWD) deflections at seven …

Most existing iterative backcalculation programs for pavement layer moduli arrive at their
solutions by minimizing an objective function related to the differences between computed …

Subgrade soil characterization in terms of resilient modulus (MR) is essential for pavement
design/evaluation. Due to the complexity of the laboratory MR test procedure, highway …

Backcalculation of pavement layer moduli refers to the process of evaluating the pavement
layers using pavement surface deflections. The genetic algorithm (GA) technique was …

The management of roads, as well as their maintenance, calls for an adequate assessment
of the load-bearing capacity of the pavement structure. This serves as the basis on which …

Subgrade soil characterization expressed in terms of Resilient Modulus (MR) has become
crucial for pavement design. For a new design, MR values are generally obtained by …

This paper introduces a frequency-domain back-calculation program, BKGREEN, that can
be used to determine the elastic modulus for each pavement layer. The pavement is …

The need to estimate the properties of layered elastic or viscoelastic media arises commonly
in various engineering applications, including geotechnical site characterization and …
