Prediction models in mobility and transportation maintenance systems have been
dramatically improved by using machine learning methods. This paper proposes novel …

Traffic speed deflectometer (TSD) provides an efficient way for evaluating pavement
condition. The current principle is to convert measured deflection slopes into the deflection …

Highway organizations need an accurate evaluation of the overall condition of the pavement
to make appropriate maintenance decisions. However, existing specifications only consider …

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 …

This study intends to compare deflections obtained from traffic speed deflection devices
(TSDDs) with the deflections of the falling weight deflectometer (FWD). For this purpose …

An equivalent relationship between stationary dynamic load and moving vehicular load is of
necessity and importance for the fact that pavement responses from nondestructive testing …

Deflection is an essential parameter for pavement structural condition assessment. For the
total pavement section length, sample size for deflection data is relatively small, which …

Soil, or soil structure modulus of deformation, is one of the main design parameters for road
engineering and traffic infrastructure design of, for example, highways, railways, runways …

State departments of transportation recognize the need to incorporate pavement structural
condition in their pavement performance models and/or decision processes used to select …

It is challenging to find actual standard test roads (ASTRs) to evaluate the measuring
performance of the Traffic Speed Deflectometer (TSD), leading to misjudgment of its …
