ABSTRACT Concrete rail ties are resistant to erosion if an abrasion resistant composition is located in a recess of the tie in the rail seat locations. A suitable composition comprises primary abrasion resistant aluminium oxide particles of uniform size and secondary particles of aluminium oxide of a uniform size equal to the voids formed between closely packed primary particles. A finer material such as silica flour is also used and the particles are bound together with an epoxy resin.
