Estimating the term…
A railroad bed and method for making, wherein a less compact asphalt layer is spread on top of a more compact one, a trough shaped ballast bedding element suitably of reinforced concrete is placed over the aforementioned asphalt layers, a slab bearing the rails is applied into the trough-shaped ballast bedding, and an elastic, plastic-modified bituminous mortar is injected into the space between the slab and the ballast bedding element.
A method for preparing a railway roadbed, comprising providing a first compact asphalt layer, providing a second asphalt layer on said first asphalt layer, said second asphalt layer being less compact than said first asphalt layer, providing at least one ballast element on said second asphalt layer, providing at least one rail supporting slab on said at least one ballast element, each said slab having a length and each said ballast element having two ends, arranging each said slab on each said ballast element in an overlapping manner so that the mid-point of said length of each said slab is substantially aligned with one of the two ends of each said ballast element, and injecting a polymer-modified bitumen mortar between said slab and said ballast element.
A railway roadbed, comprising a first compact asphalt layer, a second asphalt layer arranged on said first asphalt layer, said second asphalt layer being less compact than said first asphalt layer, a plurality of trough-shaped ballast elements arranged on said second asphalt layer, a plurality of rail supporting slabs each arranged in a partial overlap over two of said ballast elements, each said slab having a length and each said ballast element having two ends, each said slab being positioned over one each said ballast element so that the mid-point of said length of each said slab is substantially aligned with one of the two ends of each said ballast element, and an elastic mortar disposed between said slab and said ballast.
