Abstract: Surcharge preloading is a suitable foundation treatment for high-speed railways in soft soil regions. As a temporary preload on the foundation, the surcharge load must be removed before track construction. In this process, ...

Abstract: This paper primarily focused on the dynamic tribology properties of one certain nonasbestos organic (NAO) friction material by using an approximate in situ method. This study was performed through a pad-on-disk type friction ...

Abstract: Track degradation and defects of existing passenger and freight mixed railroads are concentrated in bridge–embankment transition zones. Heavy axle load (HAL) operation on existing railroads presents a complexity in evaluating ...
