The properties of railway ballast material are affected by the local geologies and climatic
environments from which the parent rock is sourced. These factors can make it challenging …

Human activity has required, since its origins, stones as raw material for carving,
construction and rock art. The study, exploration, use and maintenance of building stones is …

Background This article deals with a unique topic related to railway infrastructure, civil and
geotechnical engineering, and modern materials. In the past 20–30 years, more and more …

The collision and friction between the coarse solid particle and the concrete surface are the
main reason for the abrasion damage of concrete structures caused by debris flow. Fibre …

This article summarizes the research results related to our own conducted extensive
laboratory tests of polymer composite and steel fishplated glued insulated rail joints (GIRJs) …

Construction aggregates derived from primary resources either by crushing of sound rock
masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments …

Railway ballast deteriorates over time due to cyclic loading and environmental factors,
necessitating its replacement to maintain track stability. However, the potential shortage of …

Quarries are very abundant in Tetouan and Fahs-Anjra provinces as well as in the M'diq-
Fnideq prefecture of Northern Morocco. Their growth is proportional to that of the economic …

The current paper concerns the investigation of CC (Concrete Canvas), a unique building
material from the GCCM (geosynthetic cementitious composite mat) product group. The …

The performance of the ballasted permanent track is linked to the quality of the aggregates
that make up the ballast layer. This layer is the only one that allows the regularization and …
