The invention relates to a concrete material for a carrier layer of a ballastless railway or tramway track, and to the use of the same for produci ng one such carrier layer. The aim of the invention is to use said material to enable a significant reduction of the manual work required until now for the assembly and compaction work especially for superelevations in the bends of the track. To this end, the concrete material contains 240 - 280 kg /m3 of limestone powder, and 1500 - 1700 kg/m3 of aggregates, said aggregates consisting of 35-45 % of aggregates having a particle size of between 0 and 2 mm, 25-35 % of aggregates having a particle size of between 2 and 8 mm, and 25- 35 % of aggregates having a particle size of between 8 and 16 mm, the number of the consistency class decreasing by reducing the part of solvents, as the geometrical cant of the carrier layer of the superstructure increases.</SDOA B>
