Abstract (en)
[origin: WO2010031099A1] The invention relates to a track supporting layer (1, 1'), which in the form of a series (27, 27') of such consecutively arranged track supporting layers forms a basis for the rails (9) of a track. The track supporting layer has the shape of an isosceles trapezoid, the legs of which define the course of the faces (2, 3) of the track supporting layer (1, 1') and the mutually parallel sides of which define the course of the lateral surfaces (5, 6) of the track supporting layer which extend in the longitudinal direction. The channels (8) running between the faces (2, 3) of the track supporting layer have a bent or arched course. The concave side (16) of this course faces the shortest lateral surface (6).
