Functions of the Railroad Gravel Ballast Prism and Requirements for it
Journal Title: Jaunųjų mokslininkų darbai - Year 2013, Vol 39, Issue 1
Abstract
Ballast particles breakdown and deteriorate progressively under heavy train cyclic loading. Breakage of ballast is always associated with railway track deformation, which requires costly regular track maintenance in the form of replacing the degraded (recycled) ballast with fresh aggregates and subsequent re-compaction (tamping). The ballast has a significant impact on the quality and strength of the track. On this basis, many special requirements on it are raised. Some of them are very important both in structural and in economic terms, and other less significant, or they are fully implemented (adapted). In order to rationally plan the further multidimensional researches on ballast prism and its materials, it is necessary to review and systematically discuss the arising problems. Scientists analyze and present the results of researches not only on the overall railway transport system, but also specifically on its individual components. In this paper, functions of the railway road gravel ballast prism and requirements on it are analized. The results of world scientific works are studied and their applicability to the conditions of Lithuania are discussed.
