Abstract The functional requirements on surface layer of foundation bed for high-speed rail?ways are rather more strict than for ordinary railways. In other countries,the stabilized layers with various structure forms which are different from the traditional mode have been adopted as the surface layer of foundation bed for high-speed railways,but the engineering costs are raised consequently. Therefore，it is very necessary to select a reasonable and economical sta?bilized surface layer which is suitable for the conditions of our high-speed railways. The tech?nology, strength and other properties of a dry-hard soil material stabilized by cement are re?searched in this paper. Based on the research，the realizability of using this material as the surface layer of foundation bed for the high-speed railways has been discussed.
