STUDY ON BEHAVIOUR OF COMPOSITE SLEEPERS

Abstract

Railway sleepers have important roles in the complex railway system. Due to different loading condition, poor maintenance of sleeper or bad quality of ballast, a random load distribution along the sleeper-ballast interface may occur. A sleeper design, and also the track system design, which do not consider the random load distribution, could influence the performance of the sleeper and even damage the whole railway system. Results of suitable materials for replacing regular railway sleepers materials, vertical displacement of rail seat, stress at midpoint and underneath rail seat are presented. Moreover, the safe moment condition is also identified.
