Falling weight deflectometer backcalculation is a structural health monitoring approach for
estimating the dynamic modulus of flexible pavements. It consists of two key aspects: a …

The use of falling weight deflectometer–based backcalculation techniques to determine
pavement layer moduli is a cost-effective and widely used method for the structural …

Abstract Quarry By-products (QB), usually less than 0.25 in.(6 mm) in size, are the residual
deposits from the production of required grades of aggregates and are often stockpiled in …

Thermal cracking is one of the main asphalt concrete distresses. Asphalt pavements
typically experience thermal cracking at an early stage of their service life. The Mechanistic …

Conventional flexible pavements built on lime stabilized soils (CFP-LSS) were studied for
the backcalculation of pavement layer moduli from nondestructive Falling Weight …

In this research study, 20 pavement sections were selected from six counties in Illinois, with
varying structural and traffic characteristics. Falling weight deflectometer (FWD) tests were …

Pavement Backcalculation process is mathematically an indeed complex inverse problem
that can be approached deterministically or probabilistically for the realistic estimation of …

Previous research studies have successfully demonstrated the use of artificial neural
network (ANN) models for predicting critical structural responses and layer moduli of …

Nowadays, automated plate load tests (APLTs) are used to evaluate the performance in
terms of deflection data obtained from different magnitudes of loading. Several back …

This paper describes an advanced pavement analysis application based on a soft
computing methodology, SOFTSYS, recently developed at the University of Illinois for …
