Modern highway engineering reflects an integrated view of a road system's entire lifecycle,
including any potential environmental impacts, and seeks to develop a sustainable …

This was prepared for the symposium as a state-of-the-art paper. The paper summarizes the
history and present use of nondestructive testing (NDT) and speculates on future …

An efficient microcomputer program for backcalculating moduli from nondestructive testing
results is described. Its use is illustrated by analyzing a typical section where several …

Backcalculation of pavement layer moduli from deflection measurements has been a focus
of recent pavement research because of the need to adopt mechanistic design and analysis …

Methods, systems, and computer program products for determining a property of
construction material. According to one aspect, a material property gauge operable to …

Recent advances in flexible pavement design have prompted agencies to move toward the
development and use of mechanistic-empirical (ME) design procedures. This report …

Methods, systems, and computer program products for measuring the density of material.
According to one aspect, a nuclear density gauge is disclosed for measuring the density of a …

The seed moduli chosen for backcalculation analysis of multilayer flexible pavements can
have significant impacts on the performance of backcalculation software and, sometimes …

This study developed a method to estimate the elastic moduli of a flexible pavement system
from Light Weight Deflectometer deflection data. The forward method (simple equations) can …

The Falling weight deflectometer test (FWD) is a commonly used method for the evaluation
of the structural performance of pavement systems. In the FWD test, a large weight is raised …
