TL;DR: In this paper, the compressive and bending strength of the investigated material is sufficient for this purpose and that the strength can be further increased by suitable curing conditions, which could contribute to the utilization of old concrete sleepers during railway reconstructions and safe money spent for the purchase of new materials and disposal of old sleepers.

TL;DR: In this article, the mechanical performance of micro-filler cement-based material produced from recycled concrete sleepers was investigated, which can be considered both as a binder and filler at the same time.

TL;DR: In this paper, the PVA solution was added into fresh mortar in the amount equal to 1.4 and 2.8 % of cement weight, and the development of the dynamic Young's and shear moduli was monitored using the non-destructive resonance method during first 28 days of hardening.

TL;DR: In this article, the use of asphalt concrete (AC) for railway trackbed layers is now well established and, in some countries, even accepted as a standard solution for high speed or high load lines.

TL;DR: In this article, a fly ash-based stabilizer was used in the track bed of a railway line. And the results from non-destructive methods of Micro-CT and of electron microscopy were performed on specimens for the purpose of displaying their microstructure and identifying non-homogeneities of the specimens.
