Influence of mixture composition on fresh concrete workability for ballastless track slabs [PDF]
E3S Web of Conferences, 2020 There are several factors that affect the fresh concrete workability: water demand and composition of Portland cement, properties of fine and coarse aggregates, presence of superplasticizer and others admixtures, etc. Influence of quantity and fineness of ground quartz additives as well as polycarboxylate-based superplasticizer amount on workability of

Simulation of Delamination Evolution of Slab Ballastless Track under Vertical Impact [PDF]
Shock and Vibration, 2021 During the running of a high‐speed train, the wheel may bounce on the rail due to the track irregularity. The wheel bounce could generate a vertical impact, leading to the initiation and expansion of delamination between layers of the track structure.

Collision derailments on bridges containing ballastless slab tracks [PDF]
Engineering Failure Analysis, 2019 Train derailment on bridges is an infrequent event, yet when it occurs, it's usually catastrophic. These incidents can toss-out part of the derailed train from the bridge deck and collapse whole or a part of the bridge. Understanding the derailment mechanisms of trains on bridges and identifying the dynamic characteristics of bridges subjected to the ...

Concrete mixtures with high-workability for ballastless slab tracks
Journal of King Saud University: Engineering Sciences, 2017 The concrete track-supporting layer and the monolithic concrete slab of ballastless track systems are made in-situ. For this reason the concrete mixtures of high workability should be used.

Transverse Oscillation of a Base Slab Section of Ballastless Track
World of Transport and Transportation, 2019 The study is devoted to construction of a mathematical model of a slab of a ballastless base of a railway track, assembled from separate segments fastened together. Each rectangular segment is modeled by a transversely isotropic prestressed plate. An equation has been obtained that allows researchers to study the natural oscillation frequencies of a ...
