The CRTSI isolated slab consists of a prefabricated track slab on a track mat (t=27 mm). The height adjustment was carried out by CA mortar between the track mat and the first concrete. The stiffness of the mats was adjusted in three steps, ensuring a smooth transition from the CRTSI isolated slab track to the standard slab track.
