Railway ballast beds bear cyclic loadings from vehicles and deteriorate due to ballast
particle degradation (breakage and abrasion), ballast pockets (subgrade defects), fouling (or …

Improving the resilience of infrastructures is key to reduce their risk vulnerability and mitigate
impact from hazards at different levels (eg, from increasing extreme events, driven by climate …

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 …

The track line suffers from track irregularity, subgrade settlement, rail surface defects, and
gauge distortion. Measuring the track geometry quality plays an important role in rail …

The estimation of track degradation rate is a challenging step in scheduling preventive
maintenance interventions due to its uncertain nature. To tackle this challenge, a large …

This paper addresses the use of nondestructive Ground Penetrating Radar (GPR)
methodology in the investigation of railway ballast under a diverse set of fouling and …

Obtaining geometric information of rock aggregates is a requisite process for numerical
simulation and experimental investigation of their macroscopic and microscopic properties …

Measurement process in railways is an expensive and difficult task which involves several
steps. In some cases, costs can be reduced by using conventional devices such as …

Effective progress control is vital for steering infrastructure construction to completion with
minimum delay. Walking through the infrastructure project site to record progress in different …

Surveying railway special grid (sRSG) pins were integrated with terrestrial laser scanning
(TLS) targets and near-field communication to develop an optimised and universal …
