Degradation and fouling: High contact forces and ballast layer vibration can increase the ballast wear rate, which results in an increased volume of fines within the ballast matrix. These result in more rapid ballast settlement rate particularly in wet conditions. For high-speed railways, ballast abrasion is a common degradation type, …

Abstract The non-uniform shape and diverse dimensions exert a substantial influence on the distribution of forces within the ballast, hence affecting its bearing capacity. The objective of this work was to investigate the interrelated impact of particle shape and size on ballast strength, and then construct a prediction model that could estimate the …

Optimal track conditions rely heavily on ballast maintenance. Ballast doesn't always get the attention it deserves. For those outside of the industry, the flashy signals, rail and crossties are what railroad lines are made of. But those tiny rocks are what keeps the track in place and aids proper drainage, two important staples of a good trackbed.

Ballast is generally defined as a volume of graded crushed rocks, however many other materials have been used or developed to serve as ballast [1].It is typically laid in a compacted layer, generally 250–350 mm thick, as shown in Fig. 1.It has the following functions [1], [2], [3]:. Resistance to the sleepers against vertical, longitudinal and lateral …

Breakage modeling of ballast particles in the discrete element models is the main concern of ballast plastic deformation modeling after several loading cycles. In this study, a series of single-particle crushing tests were performed on 700 ballast particles to provide a set of numbers of crushed ballast particles with different sizes after ...

The crushing of ballast particles is governed by their fracture strength, mineralogy, shape, and size [6], [7]. Raymond & Diyaljee [8] indicated that ballast particles may be degraded through three possible mechanisms: (Ⅰ) breakage into similarly sized pieces (fragmentation), (Ⅱ) angular projections, and (III) wearing (Fig. 1). ...
