DEVELOPMENT OF ULTRARAPID-HARDENING CEMENT-ASPHALT MORTAR FOR GROUTED-BALLAST TRACK STRUCTURE

Y. Harada

Abstract

A new ultrarapid-hardening cement-asphalt mortar as viscoelastic material for the grouted-ballast track structure which will render the existing railroad lines maintenance-free has been developed. Its various characteristics have been investigated in various experiments to make it practically available. Ballast applicability, efficient work method and appropriate measures for correction of track irregularities have been established.
