Abstract

A new type of railway sleeper made from composite materials is now being developed to replace deteriorating timber sleepers. To protect it from unfavorable environments and to increase the strength at rail-seat area, the sleeper is coated with epoxy based polymer concrete. This paper investigates the properties of the polymer concrete matrix with different percentages of epoxy resin binder and lightweight particulate filler. The mixing proportion of Particulate Filled Resin (PFR) was optimised while targeting a specific strength and workability. The content of epoxy resin was varied from 40 to 100% whereas the filler material ranged from 0 to 60%. The flexural performance of PFR was evaluated using three-point bending tests and the most suitable mix proportion is determined based on the experimental results.
