The sub-ballast layer plays a key role in railway track performance, especially under heavy haul conditions such those of the Carajás Railway (EFC) – Brazil, where axle loads are expected to increase to 40 t/axle – a level ...

High-Speed Railways provide efficient transportation but impose significant dynamic forces on ballasted tracks, accelerating ballast degradation and increasing maintenance demands. This study aims to understand and mitigate ...

Road pavements are vital for transportation infrastructure, yet they deteriorate over time due to traffic loads and environmental factors, resulting in cracks and damage. This paper introduces an innovative method for crack ...

O artigo apresenta uma compilação de exemplos nacionais de investigação, desenvolvimento e inovação relacionados com a transição verde e a transformação digital no âmbito da geotecnia nos transportes e associados às ...

The structural evaluation of heavy haul railroad tracks has always been sought by engineers and researchers to achieve better-performing structures to satisfy the constant need for higher transportation capacity. Physical ...

The increasing demand for the development and expansion of transport infrastructures requires alternative solutions that are economically and environmentally viable to provide the necessary raw materials. Transport ...

Railway infrastructure is essential for transportation worldwide, and ensuring its safe and efficient operation is of utmost importance. The ballasted track system is still the most common railway infrastructure type, ...

As transições ferroviárias, como as entradas em pontes ou passagens inferiores, são locais onde frequentemente se desenvolvem defeitos de geometria de via, que podem colocar em risco a segurança da circulação ferroviária ...

Electric Arc Furnace steel slag aggregate has potential for wider application in transport infrastructures. However, the use of steel slag aggregate in the railway ballast layer, as an alternative to natural high quality ...

Photogrammetry-based methods using everyday, easily available photographic equipment and free software have gained relevance for roughness measurement of rock joints. However, the influence of some aspects, such as the ...
