Statistical analysis of cone penetration resistance of railway ballast

EPJ Web of Conferences, 2017
Dynamic penetrometer tests are widely used in geotechnical studies for soils characterization but their implementation tends to be difficult. The light penetrometer test is able to give information about a cone resistance useful in the field of ...

A Machine Learning Approach for Forecasting Rail Degradation in Railway Systems

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
In railway systems, the contact between rolling stock wheels and rails causes continuous wear, requiring periodic rail replacement to ensure operational safety and reliability. Traditional methods to estimate rail lifetime often fail to account for the specific conditions of each railway, leading to inaccurate forecasts.

The influence of membranes on tests of coarse-grained materials at low cell pressures

, 2014
In triaxial tests on small specimens of sands/silts and clays, cell pressures are usually greater than 100 kPa and membranes are relatively thin (~0.3 mm).

State‐of‐the‐Art Technologies Integrated With InSAR: A Focus on Structural Health Monitoring of Railway Infrastructure

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Interferometric synthetic aperture radar (InSAR) processing is widely implemented to remotely inspect linear infrastructure, such as railway tracks, enabling a wide range of spatiotemporal coverage. Despite InSAR is nowadays integrated with other remote sensing data and in situ measurements to establish structural health monitoring systems of railway ...

Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]

, 2016
The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...
