Usage Analysis and Evaluation of Slab Track Constructions

Abstract

Slab track is one of the technical possibilities to achieve the following goals: increase the conductivity of a railway, increase the highest permitted train speed, reduce the cost of railway maintenance, and increase the railway lifetime. However, the abundance of slab road constructions that occurred during the development stages presents a challenge to railway operators, designers and researchers, about the selection of a right slab track and establishing requirements to it. The present article analyses the ballastless track constructions that are used in the European Union and other world countries. The market is analysed, and a comparative evaluation of the ballastless track construction is carried out, based on the quality and price, by rating and providing the evaluation of usability and recommendations.

Impact Assessment of Asphalt Concrete in Geogrid-Reinforced-Pile-Supported Embankment During High-Speed Train Traffic

“…However, minimizing structure vibration to improve passenger comfort remains a fundamental concern in research. Some studies were conducted to optimize the dynamic of railway system response through the structural design, maintenance and modernization of the railroad system for high-speed trains (Chango et al, 2019;Gailienė & Ramūnas, 2019;Liu & Shao, 2011;Zakeri et al, 2017). Through the experimental test, Sysyn et al (2019) showed that the ballast layer consolidation significantly influences the distribution of stresses under the sleeper.…”
