The roadbed is the most deformable and most heterogeneous component of the railway
track infrastructure, which state is the main factor determining the efficiency of the road, and …

Railway ballast performance is dictated by a complex mix of mechanical properties. These
effect its performance at the particle level for example in terms of particle degradation, but …

Ballast plays a vital role in transmitting and distributing the train wheel loads to the
underlying track substructure. The load-bearing capacity, safe train speed, and the levels of …

In the past 20 years, many studies have been performed on ballast layer inspection and
condition evaluation with ground penetrating radar (GPR). GPR is a non-destructive means …

Mud pum** under railway tracks has received increasing attention from academic and
practical perspectives in recent decades, however, the actual mechanisms and possible …

Track transitions such as bridge approaches, road crossings and shifts from slab track to
ballasted track are common locations where track degradation accelerates due to dynamic …

This paper presents the results of field and laboratory studies of slurry tracks along the South
Coast rail line in NSW, Australia. Site investigations on fouled tracks were followed by a …

While many studies focused on both new and fouled ballast behavior due to contamination
by external fouling agents, far fewer studies have focused on the mechanical breakdown of …

The rail network plays an essential role in transport infrastructure worldwide. A ballasted
track is commonly used for several reasons, including economic considerations, load …

To facilitate rapid, accurate, and convenient detection of ballast fouling, this paper proposes
simplified computational models based on thermodynamic principles to analyze the surface …
