DESIGN AND EARTHWORK OF CUTS AND FILLS FOR CONCRETE SLAB TRACK UPON SUBGRADE

A concrete slab track upon subgrade has been studied principally by the Ballastless Track Group of R.T.R.I., JNR. Fills for concrete slab track must be made carefully and a nature ground is limited on the good place on laying slab tracks. On cuts for slab track, a displace layer is important factor. The thickness of a displace layer is designed by the liquid limit of the cut ground. The subgrade for concrete slab track is used a better material than the fill and it is necessary that it is compacted by the enough energy for earth work.
