Railway ballast

Railways play an important role in current transportation systems. The ballast bed (granular layer) is placed between the sleeper and the subballast as a shock absorber to reduce the stress from sleeper to an acceptable level (Fig. 14.1).Ballast bed is made of crushed rocks of certain size (in 20–60 mm range).Among the track components, ballast is the biggest part of …

Effects of Particle Size and Grading on the Breakage of Railway Ballast

Ballast is coarse aggregate with particle size normally ranging from 10 mm to 65 mm. Upon repeated train loading, ballast deteriorates in the form of either continuous abrasion of sharp corners or size degradation, which have been reported as the fundamental cause for the instability of railway tracks. In this study, the splitting behavior of ballast grain with varying …

Railroad Ballast Density Measurement

Abstract. Because existing methods were unsuitable for measuring the in-situ density of railroad ballast, studies were conducted to develop a new technique. A laboratory investigation was made of the various factors affecting the measurement of density in railroad ballast, which typically is composed of open-graded and coarse-grained aggregates. An approach employing water …
