Design of Abrasion Resistant Concrete Railway Crosstie Rail Seats

Record Type: UTC
Concrete railroad crossties are well-established within the North American railway industry as an economic and effective means of providing vertical and lateral track restraint and transferring axle loads to the ballast and subgrade. There are, however, notable deficiencies in their service life and overall performance under the repeated heavy-axle load environment seen on high-density freight rail corridors in North America. The objective of this work is to increase understanding of the mechanism of abrasion, determine the role of different combinations of rail seat and tie pad materials on the occurrence of abrasion, and develop rail seat surfaces that are resistant to abrasion. This project will involve the refinement of an abrasion model that will act as a design tool for future concrete tie mix designs and tie pad materials.
