Review of failures of railway sleepers and its consequences1st International Conference on Infrastructure Failures and Consequences (2014)
AbstractRailway sleeper is one of the important structure that having problems with high maintenance and replacement costs owing to its early failure. This paper presents the causes of failures of the traditional railway sleepers particularly timber, concrete and steel, and discussed its effect on the railway industry. The review of literature indicates fungal decay, end splitting and termite attack are the typical causes of timber sleeper failure. In case of concrete sleeper, deteriorations are observed because of rail seat abrasion, longitudinal cracking, high impact force and chemical attack. Failures in steel sleepers are mainly due to corrosion and fatigue cracking at the rail seat region. These unexpected failures of sleeper significantly increase the track maintenance costs. This paper also presents some recommendations to minimise sleeper failures for their safer usage.
